British Rail Class 350 25kV Electric Multiple Unit (EMU) 350372 shortly before boarding in anticipation for the 1W09 10:49 (10:49 RT) 'London Midland' London Euston- Birmingham New Street service train at Euston Station in London (UK).
The Class 350 is part of the Siemens Desiro family of EMU's.
Note the Dellner type coupling system at the front of the train. The Dellner Coupling is a version of the Scharfenberg coupler which connects pneumatics and electronics at the same point of contact.
The energy absorption technology in a Dellner Coupling allows collisions at speeds of up to 9 mph with no structural damage and up to 22 mph with deformation while the carriages remain on track.
