No surprises that the 375 fleet gets busy in the peak hours, but it has revealed a rather odd quirk of the powered internal doors between carriages.
They are equipped with the usual press-buttons to activate them - nothing strange there. However they also have a movement sensor fitted at the top, presumably to ensure that they dont close on any unfortunate soul.
But the sensor also works to activate the door. So on what is primarily a commuter fleet, anyone standing near the door during busy times causes it to open and shut constantly. Even turning the page of a newspaper has this effect.
I'll admit it's hardly the end of the world but it did strike me as puzzling. Why fit buttons and sensors? Or why not just limit the sensor to activate during the closing sequence, ie to prevent accidents.
Unaware if 377s have a similar arrangement...............
