Been trying to crack the code: GCC - R7 03 G: Great britain CC: class 483 Electric DC (including Battery) R: Isle of wight 7 : the route is set in 2011+ 03: if im right, Bcuz Northern Trans-Pennine is GDF-R5 01 and Tees Valley Line is GDF-R5 02, with IOW being GCC-R7 03, it would mean Eeast Coastway(GCC-R7 01) and IOW are ''close''. What route would be GCC-R7 02?? First influence is the R7 and after G https://forums.dovetailgames.com/threads/cracking-the-code.25968/
Could it be 03 because the SouthEastern High Speed route is 02? Although I'd have thought that'd be BC because has AC and DC electrification. It's interesting to see that they've gone with 2011+ for the era as the trains are in the early 90s livery but the route itself is modelled from the modern day.
