Create a Thameslink Route...either from Luton to Brighton or Cambridge to Brighton...it would be great!
Both of those routes are very long routes, so DTG making them is very unlike even though both routes would be a nice addition to the game. They would probably have to shorten it at both ends to make it possible.
I think maybe Brighton to Norwood Junction/Selhurst would be best because that can include Southern and Gatwick Express services.
I'd like to see a London - Brighton route with Southern and Gatwick Exp running services from Victoria, and Thameslink running services from London Bridge.
I'd like to see Sutton to St Albans City, with both directions round the Sutton loop. I have more information on the route in my previous suggestion: https://forums.dovetailgames.com/threads/thameslink-sutton-st-albans-city.23373/#post-141813
That does seem like the most reasonable section to make, it could include trains that don't go through portals and semi-fast services with 12 car trains. As well as a power changeover. If you like his his thread then feel free to look at my suggestion for the same section here.
A London to Brighton would be a good bit of Thameslink/Southern.As previously said it could be a link for the ECW. Saying that she Bedford to Brighton would be fun for me as I’m ex FCC/Thameslink platform staff
