Bandai B-Train Shorty

Recommended Posts

Yeah, this is how my ones look:

As you can see, there is a two-piece chassis that has fixed bogeys.  You just put the wheels and the bogey covers in, but the bogeys cannot rotate and they cannot be removed either.

 

There is a set of 3 Bandai chassis on eBay (like the one I posted previously). They are a bit expensive, but should I get them? I would still need a fourth one with a power unit, but at least it's a start. And could the Bandai trucks be replaced on those to Kato ones if needed?

You can PM me if you want some. Got a little bit carried away with putting interiors into trains for the last couple of weeks. Got to say it's getting harder to find stuff on YAJ unless you're willing to spend some big bucks. I've been losing quite some auctions on b-trains lately.

The earlier style one-piece passenger car chassis fit in the bodies that come with the non-functional 2-piece ones.  Some later production runs changed chassis types from their original release.

Back in the spring, I lucked into auctions for a couple of big lots of just the chassis.  The other way to get them cheap is to search through the low-priced sets of cars.  Usually the photos include a shot of the underside, and you can see which type of chassis they have.  A junk lot going cheap has perfectly good chassis, and if your lucky you can find ones with Kato bogies already included.  These are usually way cheaper than what the T-Kai sets fetch.

Power Unit prices jumped up quite a bit in the early spring too, and have not come back down.  The 7,000+¥ listings are still ambitious and keep getting re-listed.  But going rates are now pretty firmly in the 6,000¥ range.  But again, also look at sets of cars and read the descriptions carefully: if it says 'runs well' etc., then there's a Kato or Bandai power unit in there!  If you know what one of them looks like from the bottom, you can tell which it is from the photos.  I lucked into a full 7-car E653 Fresh Hitachi set for the cost of what the included Bandai power unit and Kato trucks would have cost — the 7 Shorties were free!

Well, I ended up buying that set of 3 Bandai chassis from eBay, after all. So I will just need to get a power unit somewhere.

 

I guess I should either get a Bandai power unit so they all match, or get a Kato power unit and replace the bogeys on the other 3 Bandai chassis with Kato bogeys - the Kato bogeys fit on the Bandai chassis, right?

Do you have power units as well, maybe? I will try to check some other sites first, but if I don't find any on the internet, I may be interested in one.

That's sounds like a nice find. Sometimes I'm also thinking about trying to get into the japanese Yahoo auctions. Not related to only this, but for car parts as well and such (I have an old Nissan that sometimes is hard to find parts for).

The Kato power unit will couple just fine to the bandai unpowered chassis, so you don‘t need to swap anything out on those. Just get a Kato power unit and you should be fine 🙂

 

For japanese auction bidding just take a look at zenmarket.jp.

Oh yeah, it's not the couplings I'm worried about, just the fact that the bogeys are different on the Kato ones - so I would end up with 3 cars looking the same and 1 different. Not that big of a deal, but it would bother me a bit. Though it's likely I'll settle for a Kato unit anyway, as they seem much easier to find, lol.

 

By the way, why are the Kato ones preferred over the original Bandai ones? I remember I've read that they run better, but why? Are the Bandai ones more likely to derail themselves, or simply have worse performance?

The Kato ones have 4WD, the Bandai ones have 8WD. The only real advantage of the Kato ones is availability I‘d say.

 

And yeah, I totally forgot about the bogie design. 11-105 looks the closest from afar but if you know they‘re different it‘ll bug you, I know that feel 😄

Sorry, I don't. I only make that one piece chassis excluding bogies. I always go to Hobby Search for KATO power units and bogies because they seem to have a steady supply.

Those are the bogie chasses.  For the 2-axle 4-wheelers, the new Kato one has a coreless motor; advantage Kato there.

Well then I will definitely try to find a Bandai power unit if I can. Also it's not just the different design of the bogeys on the Kato ones, but they also seem to have a bit shorter wheelbase, right?

yes. They have a shorter wheel base but also much smaller bogies and even the wheels themself are smaller (though it might be that I just remember that wrongly). 

Edit: didn’t see the photo above. It pretty much tells the whole story!

One caveat about the Kato 4w mechanism, you have to cut the frame down a bit to fit the under cab skirts on some locos. The rest lines up perfectly, just add some ballast weights for improved grip and pickup. The Bandai mech included those, the Kato one doesn't. Just carve a little bit at a time and keep checking the skirt against the chassis, I dismantled the loco body so I could fit the internal structure to the chassis and see where the skirts needed to end up.

I had to heavily process my ED75‘s inner structure and the Kato chassis to make them work together. Keep in mind tho that the Shorty locos were never designed for running with 4 axle chassis 😄

Regarding Bandai/Kato chassis stuff the Kumamoto 5000 I got seems to have chassis with the holes for the Kato trucks and I believe it even lists them in the instructions. I have the fixed bogies on right now but will swap the body for one over to the chassis with the holes when I get the trucks.
