I suggest that we should add a class 376 DLC on the southeastern line that goes from faversham to charring x
They don't run on this route, only on metro services within London going as far as Dartford and Orpington.
Only as empty stock for maintenance at Ramsgate depot, which don't run frequently. They are limited to services of up to 1 hour due to them having no toilets (they only go as far as Orpington and Dartford usually, or at furthest Gravesend and Sevenoaks from London).
AirbourneAlex is correct, any class 376's that operate on this route (which is my local route irl) only operate as ecs moves to and from Ramsgate depot and even then they only operate a couple of times a day.
