i recently picked up 1/2 of a TOMIX 92139 JR Electrical Inspection Cars Series 193 2-car set; the training(?) car (the one with 2 pantographs). Though it's not prototypical, I want to use it for an express locomotive for a 2 or 3 car container consist. The piece came with both the track cleaning truck and the regular truck. my 1st problem was I could not get it to move on the track as the wheels had no traction (motor works). I checked the orientation of both installed trucks and they are turning the same direction. I think I finally fixed that problem by adding traction tires. At least it moves now.
But, it will only move in 1 direction, backward. even if using the direction toggle on the power pack. it only moves backward with the direction switch in either position. Is this trailing chassis only set up to move in reverse (relative to the lead chassis)? I have not taken the motor case apart yet to check the drive train.
