Following a question I have shown my simple chassis arrangements. Its not going to please the rivet counters but then again I do not think they would use a MTK kit. The seats are old MTK ones for a DMU so are not quite correct.

The main part of the chassis is a piece of PCB board,I then soldered 2 coach W irons to it. I made a motor mount from some brass sheet and added a DC10 motor with 30/1 Romford gears. I added 2 square bits of brassbetween the W irons for added stiffness. 8ba bolts soldered to bits of brass, which were then stuck to each end of the body. A hole is cut into the PCB board to allow the worm gear into the body and part of the motor, which fits flush with the floor, a High Level kit may keep all below deck but once the seats are in place nothing can be seen

All I now need to fit are PB strips to act as wipers on the wheels, and cut the very botom part of the W irons off to hide them.

For the Bristol Railcar I may use the High Level kits PaceMaker traction pack http://www.highlevelkits.co.uk/ The good part about these kits is all you have is 4 sides so you can fit what you want to it as its up to you what you do. The floor can even be 1 piece which is either stuck or soldered in place.

Its nice to have something a bit different, and in fact could command a small diorama layout of its own. The diorama could be no more than 3' long and 6" to 9" wide, I could use 4 different railcars, 1 rail bus, a GWR and LMS push pull units. A bit bigger then 2 car DMu & EMU could be used.
