 (AC) units to be built by British Rail, and British Rail's first EMUs to be capable of 100 mph.

Description

Twenty-three units were built in three different batches.
  • 601-608 - Two-car units
  • 611-618 - Four-car units containing a griddle car
  • 621-627 - Four-car units

Each unit had identical electrical equipment. The original concept called for increasing the power-to-weight ratio when strengthening trains from eight to ten cars in peak periods using the 2-car units, in order to make the peak timetable more resilient.

Operations

When built, units were used exclusively on Great Eastern Main Line

, with one of the 4-cars units used on the Walton section, and the remaining six cars continuing to Clacton. The Walton portion usually comprised the griddle car unit.

This continued until the late 1970s, when many of the units were reformed. The two-car units were augmented to four-car units between 1977 and 1980, with the addition of converted former locomotive-hauled coaching stock. In 1980, the griddle cars were taken out of use, reducing units 611-618 to 3-car units. They were later augmented to 4-car units during the refurbishment work.

Further use
