Well it arrived from Osaka Japan this morning. The much anticipated Baltimore and Ohio 0-6-0 tender engine made by Rokuhan. This is their first attempt at doing U.S outline in Z and they have nailed it! The USRA 0-6-0 was a standard loco ordered by the United States Railroad Administration in World War 1. The Baltimore and Ohio received 40 out of the 255 built. Subsequently it stayed in production (These locos are known as copies and many thousands were constructed) the running is faultless. in the video it is see running on the test track in the office and then on Hakuho in the workshop, both light engine and with some typical USA freight cars. It starts smoothly and slowly, Runs very slowly if required, equally well in either direction There are some things to note though. First it is designed to go round a minimum track radius of 195mm. No problem for me. Secondly Rokuhan and the guys on Trainboard are all warning that the wires that take the current from the tender pickups to the loco are really delicate and the loco should be handled with care. It does rely on the tender pickups a lot The instructions are in very good English for once and there is detailed desription on how to convert it to DCC ( I won't be bothering with that) I think his loco will do very well and hopefully it will encourage Rokuhan to do some other American prototypes https://youtu.be/CfN2Ab5VfD8?si=UN16SrOJxW_4o36c We are at Barrow show in two weeks time and will give it a good workout there regards Kev

Last summer went to Japan and felt in love Rokuhan's shorties so had to build a small layout with them. I did not have much space so I decided the layout would be a mountain railroad that climbs from a city to a Shinto Shrine. I've been all year building the layout and now that it's almost done I would like to share some photos. I know it is difficult to follow the railway through so many spirals, but will try to make it understandable. 2D map turned real: As you can see is a completely made-up railway and probably I will be mixing japanese elements that do not belong in that way. Sorry if the layout is not totally accurate. Still many small details are pending. I have already DCC-ed all turnouts and will try soon to start installing the decoders for the power chasis. Hope to finish soon and be able to take more photos and record some videos.

Warmest Christmas greetings to everyone, This is my first post on this forum, so let me introduce myself. My name is Alex, I am from Kyiv, Ukraine. I had to move to Germany after the war began in my native country. I am collector of Z scale models since 2006 and manufacturer of small series products like train models, digital decoders, load inserts and accessories for Z scale 1:220 under my own brand Zmodell since 2016. Here is my Facebook page: https://www.facebook.com/Zmodelltrains I am also a member of Z scale International Forum (Germany) and AZL forum (USA): https://f.z-freunde-international.de/memberlist.php?mode=viewprofile&u=1508 https://azlforum.com/user/565 I am also a member of Trainini Team - German online magazine about Z scale model trains: https://www.trainini.de/team And of course, I am a big fan of Japanese Railways and owner of one of the biggest collections of Z scale 1:220 Japanese trains in Europe. My collection counts numerous models from such manufacturers as Rokuhan, Tenshodo, Prmloco, Platz/F-Toys, ZJ Gauge, Akia and others. In 2019, I started developing my own digital decoders based on Doehler & Haass and ESU technology - solely for the needs of Z scale models from Märklin and AZL. In this report I would like to introduce my next development – sound decoder for Rokuhan trains. After successful development of the sound board for Z scale Marklin V320 diesel locomotive (Art. No. 88320 and 81320), based on the newest and the smallest sound decoder from ESU – LokSound 5 Nano, many new possibilities of equipping Z scale models with sound features became clear to me. Report about my sound decoder for V320 locomotive can be found here: https://www.facebook.com/100063508513124/posts/pfbid0hbX6d949KEs1mwF76HsiNUcmNHzTmvsr15bAkAJEPV3oWgp7urmzMiq2BeMihWVZl/ One of decisive factors that brought me to the idea of developing something for Japanese trains became the availability of prototypical sound projects for ESU sound decoders created and provided for free non-commercial usage by Desktopstation.net – Japanese provider of open-source DCC hardware and software that supports and sponsors creating of prototypical sound projects by railway enthusiasts in Japan. The list of sound projects is available here: https://desktopstation.net/sounds/list_eng.html While multiple unit trains is not the strongest category in Märklin’s product line, it is a major part of the whole lineup of Rokuhan rolling stock products. Furthermore, Rokuhan already showed, let me say, more progressive way of thinking in comparison to Märklin in terms of introducing digital control to Z scale. Digital command station and a number of different digital decoders for rolling stock and accessories already exist in Rokuhan’s product line. I have to admit that these products are not ideal in their current generation (especially in comparison to modern competitive products from German manufacturers), but they fit quite well within the needs of railway hobbyists in Japan, and in any case, it is better than nothing at all. One of the popular digital products of Rokuhan is a universal DCC board (Art. No. A059) that fits into all types of their passenger cars, cars of multiple unit trains and single running railcars (aka railbuses). A059 board features one good advantage: it actually combines two different devices together – locomotive decoder and function decoder for interior lighting. I fitted all Rokuhan trains in my own collection with these digital boards. As I have already mentioned above, availability of the prototypical sound project for Shinkansen 500 Series high-speed train and a number of other projects for Japanese trains existing in Z scale inspired me to start this development. And my idea was to develop a universal solution (just like A059 board from Rokuhan) which would fit into the maximum possible number of models. After making all necessary measurements of different train models, I developed the following specifications for my new digital sound board: - It will exist in two forms – long and short (corresponds to types A and D, according to Rokuhan’s specifications, see details here: https://www.rokuhan.com/products/wp-content/uploads/2022/01/A053_A059_DECODER_INSTRUCTION_MANUAL_E_f_18.4.10.pdf). Short form is derived by manual cutting off the long board; - Long form for will be suitable for the motor cars of Shinkansen 500 Series (Art. T013-x) and 0 Series (Art. T020-x) high-speed trains; - Short form will be suitable for the motor cars of the following trains: Tobu 500 Limited Express Train “Revaty” (Art. T034-x), JR 103 Series (Art. T022-x), JNR 113 Series (Art. T001-x, T003-x), JNR 115 Series (Art. T011-x) and JNR 415 Series (Art. T023-x) commuter trains. Very thin motor chassis and extremely silent driving gear are great advantages of Rokuhan trains which contributed for this development to become successful, too. The only train where it turned out to be impossible to fit the sound board is Shinkansen E6 Series – unfortunately, its cars are too small and offer too less available space inside. Also, my board is not compatible with Rokuhan’s Kiha 52 Series railcars due to the specific mounting requirements – different circuit board is needed for this type of the car. By the way, prototypical sound project for Kiha 52 is available at Desktopstation.net, too. I equipped my digital sound board with highly-effective energy storage module that has been already used in my sound decoder for V320 diesel locomotive and proved its efficiency. It is based on 2x 470 µF/16V Tantalum-Polymer capacitors and features overvoltage and thermal protection. I used the same type of the loudspeaker from V320 sound decoder – 15x8 mm model with only 1.5 mm thickness and 32Ω impedance. Luckily, ESU sound decoders support 32Ω speakers (unlike D&H models which require only 4-8Ω models). I prepared two different types of sound boxes – 1.5 mm and 2 mm thick. They are made from clear polystyrene on CNC cutting machine and airbrushed with clear lacquer in order to make them more transparent after CNC processing. Thick 2 mm soundbox is used in long sound board suitable to Shinkansen trains, while 1.5 mm one is used in short version suitable to everything else. I have to admit that I was very impressed by the quality of the sound and its loudness – all this was successfully achieved without any problems, despite very small size of the loudspeaker and soundbox. Choosing the right LEDs that would match the color temperature of the LEDs used in original Rokuhan A059 boards became a very challenging task. For some reason, Rokuhan uses cold white LED in their boards. I tested many different LEDs, and the only suitable model that provided nearly identical color temperature became white LEDs from Osram with 8200K color temperature. So, here are my new digital sound boards. This is the long version – with ESU LokSound 5 Nano sound decoder alongside and new E24 socket visible: And here is a comparison to Rokuhan A059 board cut off to the same size (Type D): The bottom side: You may notice that I used gold plating for my circuit boards, unlike Rokuhan. Also, I added “LV” and “LR” soldering pads for connecting headlights and tail lights connected in anti-parallel – for possible non-standard usage scenarios. And here is the short variant, derived from the long one by cutting: Comparison to Rokuhan A059 board (Type A): Here are the installation samples. Everything is pretty easy here – just like with original Rokuhan digital or analog boards. This is how the sound decoder looks when installed into the motor car of Shinkansen 500 Series high-speed train: Tobu 500 Limited Express Train “Revaty”: JR 103 Series commuter train: JNR 113/115/415 Series commuter train: I have prepared a series of videos demonstrating sound features of different Rokuhan trains equipped with my sound decoders. Once again, all sound projects for all shown trains are prototypical. Note: all non-motor cars in all trains shown in the following videos are fitted with Rokuhan A059 digital boards: Shinkansen 500 Series high-speed train: Tobu 500 Limited Express Train “Revaty”: JR 103 Series commuter train: JNR 113 Series commuter train: JNR 115 Series commuter train: Notice about Shinkansen 0 Series recently announced by Rokuhan: although my digital sound board is suitable for this train, no prototypical sound project available for it. And it is impossible to create it, since these trains are not in service since 2008. Nevertheless, I will try to dig into the subject a bit more and probably to find the closest matching sound project for this train, too. I will post an update here and add a demonstration video, too. Best regards, Alex, Zmodell

I'd started to put bits of this on the 'What did you do on your layout today' thread but thought I'd split it off as I'm going to run a shadow thread on trainboard and modelrailforum as well as the layout develops. So the back story is that my current most popular Z layout is 'Republic Steel', Uniquely because Steelworks and blast furnaces look very similar the world over can be run either as USA 1950's, USA late 90's, Railblue era British or Showa steam era Japanese! Now I have had to ration the show appearances of this layout otherwise I would be out every weekend. Although it look very good running in Japanese format with D51s pulling long trains of coal and limestone hoppers and C62s and C11s on passenger services I have always wanted to model a layout more typical of rural japan, set in the mountain regions. it is going to be small, just 1220 mm x 760 mm and the plan will be for it to be split into four scenes. First will be the small wayside station of 'Hakuho' itself. The two lines running through it are two different railways. The outer track will have OHL to allow me to run Electric locos and the inner one will be steam and diesel only. Both lines will be Bi-Directional. There are crossovers at either end of the platform to allow trains to cross over. This will be the nominal front of the layout at shows. The rear of the layout will be the hidden sidings except that, as I did with Shasta, they will be fully scenically finished as a large marshalling yard. At one end the scene will be a more urban setting with a row of shops flanking the railway and it is here that the main lines will start to diverge into the roads of the sidings. I'm still pondering about the other end but there is no rush yet. to the horror of some of my fellow Southern Pacific Z modellers I took the decision to scrap the extension board on Shasta. The board featured the Dunsmuir depot at the front and a full extra four foot of sidings at the back so I could run four metre long freight trains in Z but to be honest it wasn't really working out. Transportation with the extra board meant borrowing one of the call-out vans from work and there are no show bookings for Shasta in its long form. All of the scenery was removed (you will see these trees again!) and the track recovered using copious amount of warm soapy water to loosen the ballast. The board has the advantage that it already has a wheeled flight case and I have taken off the hinged legs used when it was inserted into Shasta. So for now it is sat on my usual steel trestles ready for its transformation. Early days So here is the initial layout for 'Hakuho' with just one siding and a small shed. Buildings are by Sankei except the overbridge that came with a resin cast C57 as some sort of collectable. Marklin points and a mix of Peco and Marklin track. At either end of this section will be overbridges to act as a scenic break. rising up from the back of the station will be dense woodland with just a few other buildings. The former turntable pit will morph into some sort of lake with a waterfall going into it and a stream coming out. So the plan will be to fully finish the station scene first. One of the U.K model magazines are already asking for an article so I'll press on this summer more in a mo' Kev

As some of you will recall I started an ill-fated new layout a while back called Arkaengel. This was going to be a Russian Naval base railway in Z with a large Russian destroyer and submarine sat in the dock, Anyway, the invasion of Ukraine soon put a stop to that as neither the Exhibition organisers or the model rail magazines were comfortable with it. So it was abandoned and put in the loft and I carried on completing the rear area of Hakuho (Soon to feature in Continental modeller again) A couple of show organiser asked me "What have got new for this autumns show?" Now Tapton Junction, my new,mega British Z gauge layout is a long way off so I had a rethink about the pariah in the loft. We started to see what would get round the tight curve onto the lift bridge and soon realised that anything sat on a standard Rokuhan Shorty chassis or a modified one went around without any problem One of the streetcars and the Ford boxcab shunter under test. Both sat on unmodified Rokuhan short chassis The other decision I made was that the layout would not be tied to any specific location or Era, Basically we would run anything we liked, when we liked, so long as it goes round without derailing sat in the home office with lots of Z under test lots more soon Kev

Recently i took some pictures of my Rokuhan Z trains to send to Rokuhan to show their products running on a U.K style fully scenic exhibition layout (Hakuho) But I then got carried away ad decided to photograph them running on Republic Steel as well Republic has a few show booikings this year so was set up in the workshop for some routine maintenace At shows Republic nearly always goes out with the 1990s British stock on these days so giving the Japanese stuff a blast was fun The C11 again, this time on a local passenger I started to get an idea about following and photographing Z Japanese trains from layout to layout so got Cuyahoga out of the layout shed and carried on Rokuhan DD51s, DE10, Kiha 52s, EF 66 and a PRM Loco EF 64 make the Roundhouse a busy place More soon Kev

Every now and then this hobby of model railways throws up a pleasant surprise. one such was a delivery the other days from Holland. inside the package from shapeways, inside a drawstring black cloth printed bag (Nice touch!), was a 3D printed GE-Ingersoll Rand boxcab diesel switcher. From a design by Walt-SouthernNscale it is an exquisite representation of the early loco purchased by the New Jersey Central which still survives today in preservation. there are some layer lines visible but the amount of detail is self evident It is designed to fit the Rokuhan shorty chassis. I found that the locating lugs on the chassis, if used in the holes in the body ends, meant it sat far too high. so a simple mod was done to drop the height down. There is loads of room in the body to fit a decoder or lighting board. The extra weight certainly aids performance I don't have the heart to paint it yet it looks so good. I'm going to run it as it is at this year's shows to show everybody how much 3D printing has come on How-to video here cheers Kev

It happend that a friend pointed out to me the small printable Buildings by Brother quite at the same time as Rokuhan's Z Shorties started to become real. Using both together on a layout was the natural conclusion, so I started this project, which I'm confident I can 'finish' this year. This is the 1/300 scale mock up that I did while I was waiting for my KiHa to arrive: Nothing fancy, you see, but there's not that much space on an A5 sheet after all! And, of course, you'll have to imagine a few trees, and people, and cats, and road signs, and, and, and... I was, however, surprised how useful the mock up turned out to be, because it showed me how careful I have to place the elements to provide all the necessary clearances. A particularily tight area will be the warehouse in the upper right corner. Thak god, the KiHa hasn't really so much overhang in the outer curves as it seemed from photograps- 12mm clearance from the track centreline will suffice: So much for the moment! Michi (More food for the crawlers: Zショーティー ロクハン )

This is just a little exercise I did for the sheer fun, a little layout to run Z Shorties on (indeed, I have a serious crush on those little critters!). And this is my reasoning behind it: Most microlayouts seem to consist of a mere continuous loop, which at times can become a bit boring in terms of operation. So people sometimes also include a siding to add a possibility for some action (like, e.g., on Takashi's adorable southern coastal railroad). A train, however, can depart easily from that siding, but to arrive you'd have to reverse direction. Therefore I've added yet another siding, which gives the possibility for point-to-point operations. And, because it's not easy to build a believable scenery with two termini on such small layouts, I've cheated shamelessly and put the two end points into one single station! Furthermore, I've added a yard of a respectable size, so while one train happily turns its circles others can be conveniently parked in sight. And here's the result of my little execise: For this execise I wanted to use standard track only - no flex nor cutting to length. The upper variant turned out a bit stiff in its appearance, but the lower one already looks quite ok. The length of the various sidings should be sufficient for 3-car-trains (this seems to be the standard for EMUs/DMUs), and the platforms a dawn with 150mm length. Of course, these track plans work much better for EMUs/DMUs than for locos, but even then you can abuse them for the odd game of inglenook sidings! Michi

The weekend of March 9-10th saw the annual Keighley Model Railway exhibition in West Yorkshire in England. Now it is rare for there to be two Z gauge layouts at a show but Chris Wright was there with his 'Bullet Trains' layout and I was there with 'Republic Steel'. The show runs concurrent with the Keighley and Worth Valley Railway Spring Steam gala and I called in on the way down on Friday before setting up the show. I spotted some lads from the other layouts on the trains who had had the same idea! Chris's layout is 8ft 6" long and features sporadic lightning and thunder to liven things up. Obviously the Shinkansens are Rokuhan He has modelled it in Cherry Blossom time He also had one of the Rokuhan mini layouts on display at one end (See video) My Republic Steel layout can be run either as British Rail 'Railblue era' 1950's USA or Showa era Japanese steam due to the fact that Blast furnaces are generic and look pretty much the same the world over. For the Keighley show it was running BR to highlight the wide variety of British rolling stock that can be modelled using kit-bashing and 3D printing techniques Just 4 ft 8" long it is an easy layout to transport and display The 3D printed Class 37 has been very popular with the public. Seen here with the recently completed Cardiff Rod mill wire coil train

It Begins.

At last, I've finished the 103 series z-shorty kit by Japanese producer Aozoradensya, and I'm very pleased with it! I didn't build it out of the "box", though, those little add-ons are too much fun! And this is what I did: After a fisrt coat with red oxide primer, I've added new recessed front windows (makes the cars even more 103ish), head lights made from paper rings, and tail lights made from plastic rod.

Finally got around to examining the Rokuhan Kiha 52 diesel railcar and putting it through its paces on the usual three layouts. Nicely detailed and smooth running there are a couple of very minor issues that a couple of minutes with a paint brush will sort out and it will be really useful loco at shows. Must get around to starting the new Japanese layout now! cheers Kev

This is an easy one (at least if you can get hold of a PRMLoco WaMu 80000 or 380000), a WaKi 8000 z-shorty. If you compare the PRMLoco chassis with a KoKi z-shorty, it's obvious that the KoKi fits almost perfectly with regards to its height. Therefore, what you have to do with the KoKi is: - cut of 1.5mm from each waggon end - cut 5mm from the middle of the waggon - cut of all locators for the containers The KoKi is almost narrow enough to fir inside the WaMu body. Cutting or sanding of all embossed detail from the sides should do the trick. A quick test, whether the combination runs on the 45mm radius - it does! The body still sits a bit low, but that will change immedeately: I first glued the two chassis parts on a piece of card (instead of butt joinig them), and that lifts the body some 0.2mm up. To take possible bending stress I've also glued a strip of wood on top.

Continuing my personal reflections on the models currently available in Japanese Z I turn to the electric outline locos available. Now it was never my intention to buy any Electric locos and certainly I don't intend to put any catenary up (not after last time!) but Alison at Contikits had bought a collection of Japanese Z and was offering it at very reasonable prices. So I indulged in a Rokuhan EF 66 and a PRMloco EF 64 The EF66 in Early version livery is in the foreground with the 64 in JRF Blue and white behind. Compared to the rolling stock the PRMloco EF64 is very nicely painted and its performance was very good indeed with one small quibble which you will see on the video The pair together outside the loco maintenance shed on 'Shasta' In the video I test the locos on a variety of my layouts including young Brooklyn's Alpine layout with its evil curves and gradients and Republic Steel and most of my Japanese stock getting let off the leash on my big 'Shasta' layout. This had been out in full length form at the recent Derby model railway exhibition in Union Pacific/Southern guise This show was set in the spectacular surroundings of the original Midland Railway 'Derby' roundhouse with its unusual timber roof and crane gantries set over the turntable (Still in situ) which is now part of Derby College Link to video in a minute Kev

Following on from the 3D printed GE 70 tonners I completed last year the next designs to fit the Rokuhan Shorty chassis were two different boxcab diesel shunters both designed by Stonysmith on Shapeways. The first one was an American loco very similar to the Central New Jersey GE-Ingersol Rand loco now preserved at the Baltimore and Ohio museum and like the 70 tonners is designed to drop straight onto the Shorty chassis There is no detail below solebar level and the windors are not open The other contender is the rare British Thompson Houston Boxcab that was built for the huge Ford car plant at Dagenham in the U.K. Amazingly one survives to this day on the Kent and East Sussex railway. This has the windows open which looks a ;lot better In the video I show how to finish these locos and also include some photos of the prototypes including a really rare bit of footage of the Ford one working at the plant in 1952. I decided not to do the actual Ford livery, choosing instead a mid green as it will mainly be working the Republic steel layout. Seen here just needing the flush glazing The CNJ was also left anonymous but was painted in the Pullman green used in its early days on the railroad The trucks need another coat of black as the grey is showing through

Hi all The Rokuhan Shorty chassis has caused a lot of interest recently amongst the Z gauge community, as well as the Nm and H0f guys. but one of the easiest conversions can be done with stonysmiths 'open window' switcher on Shapeways 3d printing site I needed a couple of generic industrial diesel locos to run on Republic Steel which would not look out of place if I was running it in American or British guise. I decided to stick with the ABS printed shell rather than the 3d printed Brass one. They are never going to be pulling more than 2 or 3 ladle cars or torpedo on the layout so haulage weight shouldn't be an issue. The basic chassis straight out of the package The basic shell as delivered and fresh out of the Ultrasonic cleaning bath of warm soapy water The shell is very close to a GE 70 tonner and is a perfect fir on the Shorty. The first thin coat of primer was used to reveal the areas needed the layer lines cleaning up, not much, just some round the nose end and the cab This was one was per the print with the addition of handrails from a Marklin caboose. Exhaust stack was brass tube Now in my efforts to add detail I decided to drill out the headlamp on the other one, pushing a sharp scriber into the centre of it to give the drill bit a centre to work with I managed to punch a hole in it as the material is so thin. Some choice Anglo-Saxon swearing followed and once I calmed down I decided to add a radiator grill from Scalelink etched mesh to hide the hole. Yo be honest I actually preferred the look in this shot you can see the original couplers get in the way and can push the truck down. They are the usual Rokuhan push fit and are easily removed more in a mo Kev

I accidentally stumbled upon the e-train controller from Rokuhan. http://www.rokuhan.com/english/news/2017/07/e-train-controller-start-booking-and-introduction-for-the-e-train-controller.html http://www.1999.co.jp/eng/10478906 It's feature list: - smartphone control - wired operation via the phone audio jack - wireless operation via 3rd party bluetooth audio receivers - built in speaker in the main unit - dc and dcc support - environmental sounds installed by default Imho this is very interesting. I assume that one audio channel is used to transmit the control information, while the other is used for the speaker mono audio output. The mixed DC and DCC operation is imho a new feature from any japanese manufacturer and i would like to know how did they impement it. (i assume that either the dc/dcc commands or the raw traction drive stream is transmitted, but it's a big question for me which one as they require different levels of intelligence in the main unit) Also the audio channel input means that also PC-s and arduinos/raspberries could be connected to it.

Hi all. Just posted the review i have done on the available freight stock in Z by the three major players in the field. Starting with the Showa era 4 wheel wagons before moving on to the modern image container wagons and tank cars In a future video I'm going to look at some light weathering of some of the stock and also take a look at coaching stock when I have a few more to review (I only have Tenshodo one at present) So far then I have done C62s, D51s, DE10s and DD51s. Must get a C57! video at cheers Kev

One of my youtube subscribers enquired if i was planning on doing anymore video reviews after watching my recent DD51 production. As it happened I was but had been busy for the last few months developing my British stock for Republic steel. Now I have got over the recent flurry of exhibitions I've got a bit more time to do things. I've had the Rokuhan C11 for a while now and it is a lovely little model seen here on Republic on a mixed freight passing a couple of D51s Video at Next up should be a review of the Tenshodo D51 2-8-2s in their various forms and the Rokuhan DE10 cheers Kev
