One of the common sources of issues with a lot of DLC is storage space, and in TS1 the biggest source of problems comes around file duplication. This is particularly prevalent with British Railways Mk1 coaches. Is it possible we could look towards a set of common stock libraries where the purchase of one item of DLC gives access to one of the common libraries of rolling stock, and any subsequent DLC purchases will not result in a download of their own identical or very nearly identical content in a slightly different folder location? This would allow content creators to concentrate on producing a common set of carriages and wagons for various types and allow vast streamlining of DLC installation and file space taken up - not to mention reduce duplication of reskins etc for the relevant common stock. Thanks.
