AVLR THREE CAR SETS 1
The chassis with the original body removed. Notice the traction weights. Couplings are non standard.

Such chassis can often be acquired very cheaply.
One of the original loco bodies. In this case French which is reasonable as it is Jouef chassis.
I was fortunate to acquire four chassis of which only one turned out to have a duff motor.This is one chassis under test. Note that this chassis has the original couplings.

Others I acquired had home made fittings.
