The route from Faversham - Dover Priory via Margate is 49 miles (78km). The stations along this route are: Faversham, Whitstable, Chestfield & Swalescombe, Herne Bay, Birchington-on-Sea, Westgate-on-Sea, Margate, Broadstairs, Dumpton Park, Ramsgate, Sandwich, Deal, Walmer, Martin Mill and Dover Priory. Rolling Stock could include the Class 395 ‘Javelin’ from Southeastern High Speed route. There could also be a Class 375 and Class 465 aswell. These trains are already modelled in game and can be layered onto this route, There could also be the new Class 707’s running too.
Class 707's don't operate on this route, southeastern only use them on routes that are within the London boundary although they do sometimes go to Gravesend.
I’m biased because I spent most of my childhood living near this portion of the line, but it would be an excellent addition alongside sehs travelling through some really historically relevant tracks.
