2 Hap/2 Sap - Class 414

Essentially modern BR standard design Hals, the 2 Hap units, first introduced on the South Eastern Division in 1957/8, consisted of a motor coach to the BR 2 EPB design coupled to a driving trailer composite. They were designed for main line services so unlike the EPBs had express gear ratios. Haps were introduced on all three Southern Region divisions.

N.B. The terms '1951 Type' and '1957 Type' do not refer to building dates but to the style of electrical equipment used. The first Hap to be built was 6001 which was completed at Eastleigh in June 1957 with the first of the SR Rebuilds completed around February 1958 (reported in March 1958 Railway Observer).

In 1974 forty units were downgraded to second/standard class only followed in 1977 by a further eleven units. These were reclassified as 2 Sap. They were all restored to Hap status by 1980.
