Satellites To Blame For Faulty Doors On Electrostar

Southern have confirmed to the BBC that it's a satellite fault that locks it's trains doors.

The selective door opening monitors the position of the train via GPS and opens the correct number of doors when the train is at a station with a short platform. However, the signal strength varies meaning an accurate reading isn't always possible forcing the driver to reset the system and open the doors manually.

I have blogged my experiences of this before, see the related links for some further details...
