Out of the fleet of 25 trains required to service the East London Line part of the Overground, the halfway point for the extended trains has been reached, as 13 units are now five cars in length.
Whitechapel, Wapping – and here at Rotherhithe though – are three stations on that line where the fifth carriage doesn’t fit, (you can just make it out in this picture here). The fifth car sits in the darkness of the tunnel, and Selective Door Opening makes sure that the doors in the last carriage don’t open into the tunnel.
