Hi All, I'm having a spot of bother with a Tri-ang Railways Fowler 3F in TT Gauge, (which we are re-building into The Railway Series No.1 Thomas) the model appears to be shorting out, when we were re-building the model to have the modern electric motor, we dissesembled the wheel sets (not enteirly) I am not sure what ways they go in, What side of the wheels are isolated and which arn't? and which side go where? It would be appriciated!
From the pictures seen on the net, I see that you are working on a 0-6-0. So there would be power pickup from 4 or 6 wheels. I would start by removing th wheels and body to check the motor (and wiring). There should be no loose wiring in there. If that checks, try to figure out how the power goes from the wheels to the engine. Is it through a split frame or power pickups? I suspect power pickups that are rubbing somewhere and shorting. If you suspect the wheels, use an Ohm meter to check which wheels are isolated. I doubt you are dealing with a wheel problem...

I am out of my depth with Tri-ang TT Gauge locomotives, but my experience with steam locos is that the left rail side of the wheels should be isolated (insulated) and the right rail picks up power through the frame.
Of course, this is England, so it could be the opposite of the US...

Hello there,
The Triang TT locos were smaller versions of their OO bigger brothers. The Insulated drivers sit on a neoprene style bush and that wheel is the side that the underframe wipers on the small bakelite strip makes contact with. Strictly speaking, with Triang locos, you can place the driving wheels either way around.
The Insulated wheels have either the neoprene bush visible inside the "hub" of the wheel or are a very loose fit over the axle if the bush is. If you have to reassemble the axles, make sure that the insulated sides are the same side and are also "quartered" so that they are aligned. Effectively if the wheels on one side have the siderod pins at 12 o'clock, the other sides pins should be either be at the 9 or 3 o'clock positions The wipers when go towards the insulated side when you screw on the bakelite plate underneath.
If you need clarification, PM me and I will try to get a diagram done for you!
Cheers from Australia
