East Coastway, don't get me wrong its a good route but the timetable is incredibly off. I suggest the following: Layers The most common AI layer would ofc be the 387/2 Gatwick Express from London Commuter (for those who own it ofc) BR Class 377/2 from WCML South as a sub for the 377/4 BR Class 700 from Southeastern or for those who own the 700 Timetable I'd like to see the following: 377: AI from Eastbourne to Ashford Intl (Playable as far as Hampden Park) Playable: Eastbourne to Brighton - 2tph with no going out of map Take off the Hastings services and have 2tph going to Ore Seaford to London Victoria as a 1tph service, going AI after Lewes Eastbourne to London Victoria as a 1tph service, maybe 2, going AI after Lewes again Have these do Brighton to Seaford for 1tph 387: AI from Brighton to London (2tph) and leave 2tph as 377 700: AI trains going to Bedford or Cambridge 4tph 313: AI out of Brighton Brighton to Lewes/Eastbourne (alternating with the 377) and Seaford (1tph, again alternate) 31/52: Railtours from Eastbourne to Lewes 66: Freight from Newhaven like currently, just with a bit more freight. I'm not on about a full scenery redo or anything, just a new timetable (going in with recent trend of new timetable).
Don't think the 377/2 goes to Brighton. The 387/2 was built after East Coastway is set (it's set in 2009). There's a separate timetable which includes the 313 if you own the 313 DLC Railtours already exist between Eastbourne and Lewes. As for the freight, there's not much anyway as it's a mainly passenger oriented route.
I would sooner have an extension to Ore than have half of a route. A playable route to Hampden Park seems odd since not every service stops there.
