Matt has said in the Timetable stream that substitution doesn't work for different length vehicles. This means that with the upcoming class 313 DLC, it needs to have a new East Coastway timetable as the 3 car train cannot substitute for the 4 car 377. As this is the case, it is likely that a new timetable needs to be implemented to support the class 313. What I hope is that all Brighton to Lewes and Brighton to Seaford trains [All currently 4 coach trains] (And their return journeys) will be run by class 313 trains as per reality. With Brighton to Eastbourne trains [All 8 coach trains] continue to be run by class 377 trains. This leaves the opportunity to add additional services, Eastbourne to London Victoria services, run by class 377's, driven by the player from Eastbourne to Lewes [Platforms 1 or 2] and vice versa. This poll is about weather the community would be interested in these services added to the likely new timetable. I would be interested to hear people's thoughts. Thanks for your time.
