RE: Stagecoach North East: Upcoming Service Changes
It's a very clear and obvious service gap, so if they were well used after 4pm, they wouldn't have been dropped from service. With the main patronage being Sunderland to Newcastle daytime, I wouldn't imagine them stops seeing much use after that time (currently 16:19 departure being the first). Journeys into Sunderland after that time remain unchanged - would be more concerned if they were removed.
