Leaked Tsw Class 700/0

To me not much point if you can’t drive them as well.

 

It's kinda like the MML HST at St Pancras

 

While TL doesn't serve the East Coastway normally, the 700 has occasionally been there as part of testing - there's a couple YouTube videos of the 700 at Lewes, Hampden Park, Eastbourne etc. So, not totally unrealistic for TSW to have an ECW timetable featuring a couple ECS 700 services. Out of interest, on the subject of the 700 and the South Coast, they briefly served the West Coastway to Littlehampton, but was only very limited peak time services.
