British Rail Class 357
The British Rail Class 357 "Electrostar" alternating current (AC) electric multiple units (EMU) were built by ADtranz, Derby (now owned by Bombardier Transportation) from 1999 to 2003 at a cost of approximately £350 million. The Electrostar family also includes Classes 375, 376, 377 and 378, and is the most numerous type of EMU built in the post-privatisation period of Britain's railways. These units were built in two batches for LTS Rail, since rebranded as c2c. This train is also known as one of the worst British rail trains.
