Small N gauge chassis?
Posted: Tue Sep 02, 2014 4:12 pm
Not specifically minimum gauge, but with O9 and G9 modellers here, I am looking for a small N gauge chassis. no longer than 35mm max. The Kato chassis would be perfect if it as shorter, but there are some other small N gauge locos which cost a lot more. Alternatively is it possible to cut the Kato chassis down? Not something I would want to try but the Kato chassis is cheap enough.
I might have to resort to motorizing a wagon to push loco. Possibly a better solution, and cheaper.

The chassis under this
is 25mm overall, with a wb of 14mm.
Only 2 wheel drive, but pulls well with a bit of weight on it. The chassis used to be available separately iirc.
Just measured a Kato, it's 30mm across the outer edges of the flanges.

That was one of the models I considered. Its to motorize one of my new OO9 protected Simplex locos. as I have versions with inside visible finding a r2r chassis might be even more tricky, but that Aoshima chassis might do for loco powered version with doors closed.
I have just ordered some of the new Bachmann WW1 figures so want to create a small working diorama. A shortened D class van body will fit on Kato chassis, and still cost less than the price of the Aoshima chassis , Can't see chassis available on its own.

I am sure is here somewhere, but what are the dimensions of the Bachmann N gauge diesel shunter. It looks shorter than the Kato chassis?

You can cut down the Bandai 4w chassis much more that the Kato one. You can certainly make it a little under 40mm long, but I'm not sure by how much.
It's still reasonably cheap and only a slightly inferior runner to the Kato one

35mm is absolutely max length. The Bachmann one looks like it could be cut down, and price isn't too bad.Nothing as cheap as the Kato one though.
It is to power a protected Simplex in OO9, but if necessary I will make it a dummy and have a powered wagon pushing it.

Perhaps one of the diesel versions of these could work?
I haven't tried them and have been curious to hear how they work.
I have cut down Kato 103 chassis to 45mm, removing the coupler pockets and end beam detail. One vertical cut flush to the square segment with the screw on top at either end. You might be able to remove another mm or so from either end by milling the ends and replacing the screw with a SHCS, but I suspect you'll have a better chance of breaking the chassis than actually getting a significant length change.

I saw some OO9 models fitted with very small motors. I was told it was a Kato unit, and I think it was the original one used in the Kato Portram tram unit. I think Kato have redesigned the chassis but can't find out what it now looks like.
Also if Kato can produce such a small working chassis I see no reason why someone else should not be able to do so. Sourcing motors might be a problem but the mobile phone ones as I think are used in T gauge would be a start.
