American TT Wheelsets

American TT Wheelsets

Postby RodTT » Tue Aug 15, 2017 12:08 pm

Having decided to take the plunge and make a US-based TT layout, I'm considering ordering one or two freight car bodies from Shapeways. Can anyone suggest a supplier of wheelsets? Presumably these should be 7mm diameter across the treads?
I've found these:

but they are 8mm - any good, for say a 50ft gondola or a hopper?
I'm based in the UK.

HO Scale 24 inch wheels are exactly 33 inch TT Scale wheels. HO 26 inch wheels are very close to 36 inch TT. HO wheelsets on flush or blunt axles from Northwest Shortline (NWSL) can be regauged and the excess axle cut off. These will not be needle point bearing. Pay attention to wheel tread width, .088 or less. An HO 33 inch wheel is about 9.5 mm

7 mm wheels are very close to 33" in TT. Such cars could have 36" wheels, especially long gondolas for heavier loads.

I forgot to mention, NWSL also makes brass bearing inserts for use with soft sideframes of resin, plastic or white metal.

Speaking of wheels, I recall that some time ago, spoked drivers for steam locomotives were available in the UK. They had no counterweight. Any information on those - availability, size, tread width, number of spokes?

So what do people on here actually use for their US TT wheels/axles, and where do they get them from? European suppliers preferred if possible.

One at a time!
Joe, Fox Valley has had the TT wheelsets for a while, they actually sold out of their first run and we had a slight wait for the second run (available now!). They're nice, but the axles are a bit shorter than the Gold Coast ones, so you need to shorten up the bolsters a little to make them run properly.

Graandpa- It sounds like Romford drivers?

And Rod- Mod Muller in Germany offers RP25 wheelsets in different sizes

Muller's wheelsets are good, and 7mm wheels are available.

They are available on Ebay:

Excellent - thanks very much one and all.

There are not many TT modellers in the UK, and even less modellers of US TT. You can probably count them on the fingers of one hand (or even on one finger). Maybe this post will flush a few of them out.

I modelled in British TT (3mm scale) for over a decade and after a few years with US HO, I can't resist going back to TT but sticking with US. I've discovered there is just about enough available - not cheap, but that should stop me buying too much (in theory at least!)
