History Of The 2-HAP Units

The unit of this type preserved at Coventry is privately owned by a member of the SERA. As such it is funded entirely by it's owner but remains a welcome addition to the SERA EMU heritage fleet.

The 2-HAP fleet was built in various batches at Eastleigh works between 1956 and 1963. They were all two car units geared to run at a maximum speed of 90 m.p.h. on outer suburban and long distance stopping trains. They all had English Electric electrical equipment and electro pneumatic brakes.

The first batch comprised of 36 units introduced to traffic in 1958 and built on the reclaimed frames of withdrawn 2-NOL units using 'Southern Railway' inspired body shells as the BR standard body was too long for the NOL underframe. The driving motor brake second (DMBS) coach of the unit had a guards van behind the cab and two four bay semi saloons, the driving trailer composite lavatory (DTCL) vehicle had one full width compartment behind the driving cab and four second and three first class compartments with a side corridor the length of the car. At the inner end was a lavatory. The units, like all subsequent HAP builds were non gangwayed so passengers requiring to make use of the toilet facilities had to ensure they boarded the correct coach. These units were initially allocated to the South Eastern division but later saw use on both the South Western and Central divisions. In the 1970s their first class accommodation was downgraded to second and the units were reclassified as 2-SAPs being relegated to suburban duties. All units of this batch were withdrawn from traffic in the early 1980s. A number of the DMBS coaches were refurbished for use in other EPB units for several years further service.

The second batch of 2-HAPs comprised 42 units featuring the same traction and control equipment as the first batch but with BR standard underframes and bodies which gave a revised layout to the DTCL and placed three first class compartments with side corridor behind the cab then two toilets in the centre of the car, one for first and the other for second class passengers, with a four bay second class semi-saloon at the inner end. This batch were in traffic by the end of 1958 and construction started on the next order of 63 units of the same layout as that previously employed but with revised motor control system known as 'Camshaft' or 1957 equipment. A fourth batch of 41 units identical to the third was built in 191961 and like all previous builds was initially employed on the South Eastern division.

The final batch of 27 2-HAP units was completed in 1963 for use on the South Western division and had all the features of the third and fourth batches but with commonwealth trailer bogies at the vehicle inner ends and different window frames made of aluminium.

During subsequent years all batches saw use on the three divisions of the Southern Region. At the time the initial batch were being withdrawn some of the later units were being made up into permanently coupled pairs with the units coupled together at the DMBS end and the driving controls from those cabs being removed. The resultant four car units were classified as 4-CAP units and they were initially allocated to stooping services on the coastal routes from Brighton. They were all transferred to the South Eastern division in the mid 1980s for use on Kent coast stopping trains and suburban work.

Withdrawal of the HAP and CAP fleet was a prolonged affair with the first units being taken out of traffic in 1982 whilst the last examples, by then all on South Eastern division suburban traffic lasting until 1995.

When new all units were painted all over green broken only by the yellow stripe at cantrail level over the first class sections. Half and full yellow ends appeared in the 1960s and that gave way to all over rail blue with yellow ends during the late 60s and early 70s. All the units to remain in traffic beyond 1982 received inter city type blue and grey livery and many of the HAP and CAP fleet that survived beyond 1990 were repainted into the red, white, blue and grey of the Network SouthEast sector.


Unit 5632, which was one of the initial batch of 36 2-HAP units built to Southern Railway design is pictured here in later life close to withdrawal at the rear of a Victoria bound service at Clapham Junction.
