Class 350 Desiro

The Class 350 Desiro EMU has been built in 3 batches since 2004 and serves, and has served, with a number of Train Operating Companies, probably the most notable being London Midland. With London Midland the Class 350 was the mainstay of the franchise's intercity regional services under the wires. These trains now serve with LM's successor on these routes London Northwestern Railway. The Class 350 has also served with the now defunct franchises Central Trains and Silverlink and also with Southern but now is only in service with LNWR and First TransPennine Express.

The Class 350 is capable of up to 110mp/h (except the 350/2) and collects its power from the 25kV AC overhead wires though some (350/1) can use the 750v DC third rail too however these days only operate as AC EMUs. The Desiro family also includes the very similar Classes 185, 360444 and 450. Indeed the original batch of 350s was originally ordered as Class 450s [1].

London Northwestern Railway use the 350/1, 350/2 (which has high density seating) and the recently built 350/3. First TPE uses the 350/4.
