It all depends on a number of things.
- Are they going to replace the existing trains? For something like an American themed game, where you don’t get access to most European trains at all. If that is the case, it would make sense to mirror the existing trains as closely as possible (within reason given performance differences and year)
- Are they going to be added as additional trains? In that case the prices have to be competitive with existing trains – Is X train slightly faster than Y train in the same time period? Up the costs a little.
