I am a landscape architect and am currently working on a project to renovate a historic Ford Building in downtown Indianapolis. The project has a rail spur that (used to) feed the Ford assembly plant. There is a desire to get an old flat bed railcar to sit on this rail spur, holding a Model T Ford. My question to you all is...how big would a pre-1928 flat bed railcar be? Specifically one that would have been used to service an automobile manufacturing plant? Better yet can you give me any leads on where to actually FIND one?? In my internet research I see that the dimensions of rail cars vary greatly. We'd like to design the space as close to historically accurate as we can. Any help you can provide would be beneficial! Thank you.
