the reason I have chosen this route is because it leaves from Paddington station what we all any have so this is why I have chosen it
Would be great to have the Heathrow Express on here. Then you can virtually fly into or out of Heathrow on Flight Sim and combine it with a Train Sim trip. Beautiful.
I don't know if still the case, but the last time someone ask for heathrow express as a GWE route add on, DTG replied that probably it won't be happening anytime soon; since unfortunately they didn't made any progress trying getting licenses and stuff. But I agree that it would be a awesome addition, let's hope for the best in the near future regarding GWE content.
