As mentioned last time I planned to use a Brassmasters 7ft bogie for the none powered end of my GRW railcar. The Brassmasters bogie is longer overall than the Dapol one – you can see the adjusted one at the top of the picture. Here is the bogie in position with pick ups on the far side. The near side picks up through the bogie itself.   If all you want it a p4 railcar then you can stop here. I tested mine at this point and all seemed fine but its worth noting that the pickups  are wired the opposite way round at each end. The red wire at this end goes to the opposite rail at the other.   A bit odd!

Naturally I didn’t stop there. This is the interior without the body. That huge moulded lump has to go. The culprit is this huge motor. No idea why its this big, the thing only has to move itself and you can’t couple it to anything anyway!  The Mashima sitting on top is a 1020.The good news is the motor and its mounts simply unscrew from the underframe.  I mounted my 1020 on a  bit of 80thou plasticard and on the floor. By moving the motor back from its original position you can mount the flywheel lower too. A bit of 1.5mm ID/ 2mm OD tube meant I could use the original flywheel which contains the universal joint. The drive shaft was cut in half and lengthened with a bit of tube. There’s a small lip in its channel at the motor end that needed to be ground away. While I was hacking the chassis about I cut a hole to allow me to represent the engine. Spares from the Heljan class 128 underframe sprue did the job. Next, the interior and finishing.
