The donor vehicle for the new RPO car arrived today - a Bachmann baggage car kit. The conversion will be inspired by Mik's "MOW ex-RPO" conversion, although work will not follow quite the same path owing to the slightly diffrerent ingredients. The first thing I've failed to take into account is the length of the baggage car's trucks, which is a problem as I need to shorten the vehicle's chassis. Luckily I was planning a trip to the Risborough model show this Saturday, so a side-trip to GRS looks highly likely.
My other thought was to use the baggage car underframe for a bogie caboose, but there's not enough swing behind the steps to have bogies close enough to the vehicle's end so as to use standard arch-bar trucks. I got this to work on the drover caboose, so know it can be done; I just may have to make another plywood floor/underframe for this vehicle. Just about all the materials for the body are in hand, just needing a little work to get them all to fit together.
