When the airport station opened there was a thirty minute frequency in each direction. In those days the service was reliable with cancellations unusual unlike today and there was an electric milk float with a passenger cabin that connected with every train but sadly not many passengers. The railway operator was preasured to speed up the service between Darlington and Middlesbrough so the underused station at the airport had the service cut.
Mr Houchen is telling his disciples that a train stopping will add less than a minute to the timetable but this is noncence as a railway working timetable shows several minutes for deceleration, station dwell and acceleration so you can anticipate resistance from the railway to stopping trains unless there are lots of passengers for all of those extra flights that certain politicians and members of this group seem to like inventing.
