The RCTS: then and now
CLASS 313 EMUs have been featured frequently in the pages of both The Railway Magazine and The Railway Observer since their introduction to service in 1976. They had their genesis in the 4-PEP (Class 445) and 2-PEP (Class 446) suburban EMUs, the prototypes of which entered service in 1971. However, there were no production models.
The ‘313s’ were British Rail’s first dual-voltage EMUs, having both a pantograph for 25kV overhead AC lines and contact shoes for 750V DC third-rail systems. This gave them a huge degree of operational flexibility in comparison with older EMUs.
