There are benefits in living on the District Line when it comes to strike days.   I remember reading in John Lanchester’s admirable short book book about it that the older drivers graduate to the District Line in order to enjoy the long journeys above ground between Bromley-by-Bow and the green fields of Upminster at one end and out to Wimbledon at the other instead of having to endure the deep bore tunnels of the Northern Line.   This means that, when everyone else has to endure long traffic jams and queues for the buses, the citizens of Stepney can travel as normal from Stepney Green undergound station, purling through Cannon Street and Embankment to Charles Holden’s stately headquarters at St. James’s Park.
