Woodgrange Park station, on the London Overground.  The Barking to Gospel Oak line.  An odd mix of investment and neglect.  Shiny new station waiting rooms, an excellent and quite new PA system that can actually be understood - but trains that run rather infrequently, and that are only two cars long when they arrive - but with, so far as I can tell, a train staff of three people!

I arrive at the station at 18:43.
The display screen says the next train is the 19:05, and describes it as "on time."  I wonder what happened to the 18:50 listed on the timetable.
A couple of minutes pass, and the PA pipes up, advising that the 18:50 is delayed by 21 minutes.
A couple more minutes pass, and we're advised the 18:50 is now 24 minutes late.
I have a failure of temper and patience, and march back up the platform, intending to head for the street and seek a bus.
I glance at the display screen as I pass.  It advises the next train is now the 18:50, which it reckons is "on time".
I pause.
The PA announces the arrival of the 18:50, which glides into the platform.  All two coaches of it.
As we pull out of the station, the PA is busily announcing that the 18:50 is now delayed by 26 minutes.

This seems rather familiar.
