> Is it typical for trains to be custom made? Well, yes and no. There is a basic train set, and then it is usually customized to the operator’s needs. There isn’t really a “reference design” you can order, because nobody would order it. But the manufacturer tries to have as much commonality that they can to get some scale advantages. Metra (Chicago’s intracity rail) has ordered a few hundred of these French trains [1]. They will be push/pulled by diesel locomotives, and the “customizations” are mainly just having bicycle storage areas and wheelchair ramps on both sides that work regardless of platform height (even no platform at all). But that basic train car is used in a lot of European countries.
