Tomix 6421 cleaning car - mod to run with shinkansen feasible ??

ok i tore apart an n700 truck with the ring coupler all wheel pickup. im guessing its the same truck as on the 700 dr yellow, but these may differ some. i cant find my tomix parts catalog to see what was there, i think it came out after the other all wheel pickup trains.

 

good news and bad news.

 

good news is that bogie axle/pin assembly will fit the ring pickup and the pickup's will fit into to the chassis slots. also the coupler bar looks long enough to work with a shinkansen coupled. bad news is there are several minor size differences between them in other parts

 

one big problem you see in cleaner3.jpg is that the n700 truck is a couple of mm longer than the cleaner truck so that the wheels run into the chassis (cleaner1.jpg). you could probably take off a few mm of the chassis to make room for the wheels there.

 

another issue is that the cleaner truck rides a mm or two higher above the chassis than the n700 truck does. this might be fixed by some washers to move the ring and truck up a tad, but its going to be tricky to get it just right.

 

so while its probably possible, it is going to be quite a bit of fiddling it looks like unless one of the other shinkansens with the power ring trucks is a better fit.

thx jeff for taking the trouble to mount the bogies and take the photos - i really appreciate it

Its pretty clear that the cleaner bogie has bigger wheels, hence the height difference u r talking about

 

The closest shinkansen bogie I could find was this one (for the E series), can someone compare this with the 700/300 series bogie to see if its shorter ??

I could prolly cut off the regular couplers and use the power couplers instead

Out on the HS website I can see regular spare bogies, that are shorter&higher and can possibly work as an alternative, since the coupling ring fits pretty well.

Jeff you reaffirm what I went through with the koki's 104. Trying to change the trucks or couplers is challenging. You have to redesign the trucks or design a new coupler. Because the tolerances are so tight it will be difficult to find a bolt on replacement off the shelf unless one is very lucky.  

 

Sid, I see where you are going with this and think its a good idea to bring functionality to Dr Yellow. After thinking about it I think this might be an alternative........

 

DCCmeters.GIF

 

This is a simple circuit to extract the DC voltage from the DCC track. Afterward you can take a Multi meter and read the DC voltage.

 

The way I see it...you can place the circuit in one of Dr Yellow's car and then have the output drive a LED bar graph. 4bda4de738105_118320s.jpg. Being that the circuit reads DC voltage from the track you can run your own diags. Find places that needs cleaning or feeder issues.

 

In essence Dr Yellow will be registering track voltage just as it does in the real world. Might be easier to do this than designing a coupler.

 

just a thought.

Wow, this is really interesting, though all I want to do is run my cleaning cars with the shinkansen

I'm using traditional DC btw :)

You're welcome. First whic dr yellow do you have, the earlier one w/o the all wheel pickup or the newer one with the all wheel pickup? If its the newer you will have to use the power ring style as they are different coupler designs.

 

The height is due to the bogie sitting higher on the cleaning car, not the wheel size.

 

It's probably doable, but would take a lot of fiddling I think and some experimenting with different bogie sets.

 

Don't think the second bogies you posted will work as it does not have the power ring pin in it I think and does not have the old 700 coupler so would not work for either.

 

I think the easiest would be to get the proper 700 bogies (power ring or not) for your dr yellow, then modify the cleaner car chassis to make the bogies fit. I'm guessing the non power ring bogies might fit better, but that would require an older dr yellow.

 

Which dr yellow do you have? If you have an older I could look at tomix shinkansens thr have the same coupler to see if any of those bogies fit better. I only have the n700 to try the power ring bogies.

 

Cheers

sid,

 

ok then you will have to use the newer power ring coupler mechanism to interface with those cars.

 

like i said i think doable, but will require  a lot of fiddling.

 

still think best to just do a custom cleaning train.

If the non power conducting bogie couples well with the power one, then I could probably compromise losing on the all wheel pickup

But I think the shinkansen bogie length would still be a problem, like u showed

Unless the older ones are shorter, I'll have to end up modifying the chassis

Sid,

 

You can do it with DC too.

 

You would just set the throttle at half throttle and watch Dr Yellow read the track voltage as it makes its passes.

sid,

 

sorry the powered coupler (power ring) and the non powered (older) do not couple, pretty different design to the interlocking hook and loop, but ill see if i can get them to couple, but at first glance i doubt they can.

 

btw the power ring couplers are excellent couplers.

 

im starting to doubt any of the shinkansen couplers are shorter, but ill pull out any older style tomix i have to see, i have the old dr yellow 700.

 

modifying the chassis would not be all that bad. all it would do would be to take out the little cleaning strip holder (the semi-circle one) on one side and probably cut into the vacuum compartment where you would need to just make a little L box in the bottom corner to cover up the little chunk you would have to cut out. easy to do with a roto tool.

if I went custom cleaning train way, will 1 loco be enough to pull (or push) 2 cleaning cars, or would I need 2 ??

 

I was thinking of using the Kato EH series (8 axle) loco - am I being too optimistic ??

Link to comment

should do fine. those are pretty umphy pullers. you can always add in another loco if you need more power.

 

which one are you thinking of, i can test it here, i have 2 tomix cleaners and even a centerline roller and several of the eh locos.

EH200 or EH500 with 2 tomix cleaners

preferrably in pull mode, but push is acceptable (even if it looks ugly  :grin)

 

I was also thinking of buying a SBB re460 (one of my fave locos), but I'm not sure it'll handle 2 of the cleaners

i have the kato ef200, but my ef500 is tomix. i think the 200 and 500 have pretty similar mechanisms. ill give things a run next weekend at the club show. my second tomix cleaner car is mia right now so i can borrow one of the other member's if i cant dig the second up...

Sid,

 

i checked and you will have to use the power ring couplers if you want to mate to a all wheel power newer dr yellow. the old style tomix hook and loop couplers will not couple with the new power ring style hook and loop couplers. benefit is you keep the all wheel pickup going.

i got tomix ED 61 x 2 62 x 1

 

i can pull 2 cleaners up a above 3% grade with 1 of these ED's so i don't think you will have too much problems with these being pulled about till you get a bout 3 - 4 cleaning cars

 

heck even my little Ma C11 steam can pull the 2.

 

but yeah i don't think he could pull 3 but he may surprise me.

 

Hell for fun i'm going to try thomas when i get home. (i know for sure he won't make it up the hill though)

jeff,

1st pref to the kato EH200 - the color scheme blends well with the blue tomix i think - might as well have a fashionable cleaning train  :cheesy

 

btw, if ure ever in AZ i owe u a drink for taking this much trouble on my account

ok, my layout is a flat one for now.

Eventually I plan to build a double decker one, but that also will have < 3% grade between levels. Pics attached

Most of the videos I saw had 2 or more locos pulling 2 or more cleaners, so I wasnt sure if 1 loco is good enough for 2 of them

 

I just like running trains, so only tracks for me.

Building up my high speed train collection.
