They are the first member of the Electrostar family, which also includes Classes 375, 376, 377, 378, 379 and 387, and are the most numerous type of EMU built in the post-privatisation period of Britain's railways. They have the same basic design, bodyshell and core structure as the Turbostar diesel multiple unit (DMU), which is in turn the most common post-privatisation diesel multiple unit family, and both evolved from the Class 168 Clubman design by Adtranz. The 357s are operated by c2c on the London, Tilbury and Southend line.
