2 and 4 Pep

The 2 Pep and 4 Pep units were prototype high density units developed in the early 1970s with the distinction of being the last to carry the traditional Southern Railway/Region classification. When developed, the subsequent builds were the dual voltage 750v DC/25Kv AC class 313, the 25Kv AC classes 314/315 and the 750v DC classes 507/508. They were the first above ground EMUs on the Southern Region to have sliding doors but were totally incompatible with other Southern Region stock. Three units were built, the sole two car 2 Pep, 2001, finished in unpainted aluminium and two four car 4 Peps, 4001/2, which were finished in Rail Blue. Being incompatible with the rest of the Southern Region's stock they could only operate as individual units, or with each other. The interior of the Peps featured high-density 2+3 seating but did not provide passengers with the comfort of toilets.

The three Pep units frequently ran as a ten car train, then towards the end of the experiment some of the cars were swapped around. Above can be seen unit Nº4002 with one of 2001's cars (the aluminium one) in place of one of its own.
