Baldwin-Westinghouse Class B

[InterurbanModels]

Good news first: The Baldwin-Westinghouse Class B has passed the proof of concept stade, coming nicely from the workbench. The bad news: don't even think about putting a motor in this. The Class B is so tiny that no commercially available drive could actually fit.

Years ago someone made a Class D, a similar looking but far bigger B-W locomotive, motorized with a Bandai drive, but this drive is no longer available. I will keep on searching, in the meantime its just a rolling model (and perhaps a case to make one of this shameful motorized boxcars or cabooses ...  )

Has anyone talk to you about our Lord and savior Kato Shorty B?

IMHO, some of the best kit bash fodder ever. These chassis were the bases for my class B climax build.

This looks like a project I may want to tackle. Do you have an ability to sell these prints yet?

Kato 11-107 Driving Unit

I will purchase an 11-107 (or 105) and build something around, probably a Class D, precious 3ft longer than a class B. With some compromising around the off-center hoods this should work. But in the meantime I will prepare a Class B rolling model kit for sale (minus the 36" MTL wheel sets)

Have a look at the tomix / tomytec motorized chassis / mechanisms (they have a wider variety than Kato). They produce a slightly longer version of a similar model to yours. You would have to shorten the mechanism or 3D print one and use the parts. They run as well as the Kato

Is that a challenge?

motor AND sound, or it doesn't count.

@Jim Starbuck and @mmagliaro in a power train race? We’re not worthy.

I would add @randguest to this, also.
  He's built some very small climax's

From what I have seen on this forum that model has room for a motor and even maybe a DCC decoder.

Ha, a challenge!
"No drive" means no actually commercial available drive (Kato, Tomytec), even butchered. Of course you can make a custom drive (I did that already, but I was not amused). That's not an option if you want to make the model available for others. The off-center hood means that there is no room for a turning gear tower attached to the trucks.
There was a short Bandai 8 wheel drive years ago with very low sitting fixed worms, the next gear swiveling with the truck under it. Nearly an under floor drive. But currently there is no way to get them.
In few days I will receive a Kato 11-105, then we will see what could be done. I will look towards a Baldwin-Westinghouse Class D, 6 mm longer (in N scale) than the Class B.

Wonder if it would be possible to make an N scale Stanton drive with a pager motor. Or something like a Hobbytown with a center mounted vertical motor and 2 worm shafts to the trucks under the body.

I’d be happy to release these gears if you’d release the frame you build around it as stl’s otherwise take this as inspiration that this is doable.


These are 0.3 mod gears that are resin printable. The height of the blue box is 6.6mm 5.8mm wide. I didn’t know your axle distance measurement. I guessed it at 13mm.

The cool thing about this design is that the worms can be moved up and down the shaft easily the only thing that’d need changing is the top bevel gear. Let me know if there is interest here.

Do both worms spin the same way?

Tim,

Beautiful work! I love this kind of innovation.
The days of “I can’t build (insert specific model) because there’s no drive available for it” are fading in the distance behind us.
