Recently, I travelled on the route to Dartford from London Bridge. This route includes Lewisham, Charing X, Waterloo East, Sidcup. The route will include the popular Class 465 in its refurb interior, the class 717, TL Class 700/0, class 375, and the class 376. The route will include Charing X for the first time in TSW3. Another addition to the route will be moving boats which will travel across the Thames. This route wouldn't be hard for DTG to create because they have technically got the 465,375,700. They just need the class 717 and the class 376.
I.am presuming you mean 707 rather then 717. This would be a way to linear route imo so maybe add TL core or ateleast parts of it and add the route to Victoria. Even then I'd rather backdate it for a new southern style route
Perfect idea, similar to my one way back in February. I would still love to see one like this, it would be more handy if you could provide more info such as a route map and pictures of the trains etc. Also welcome to the forums!
