Why do certain versions of the same train not get offered as playable substitutions within a timetable, but others do? For example... Class 101 On Tees Valley I can pick from local version and Preston/Carlisle version, but not diesel legends version or NTP version. On NTP it's only the local version. On Diesel Legends it is only the local version. On Preston/Carlisle it's only TV or local version.
I know the TVL one for example, has a little marker to say the unit is from Darlington, for example. I don't know if this has something to do with it. It would be kind of weird to have a Darlington unit down in the Thames Valley for example. I guess it's also kind of pointless, except maybe the Shap one with the improvements JT made to it
Yeah, I was hoping to drive the WCMLoS one on the old NTP route in the timetable, because the new version is so much better!!
