Construction
A development of the earlier 2-BIL units, the 2-HAL units (2-car Half Lavatory stock) were so-called because only one car in each unit had a lavatory. They were built in three batches:
| Units | Built | Intended Use |
|---|---|---|
| 2601–2677 | 1938 | London to Maidstone and Gillingham |
| 2677–2692 | 1939 | London Waterloo to Aldershot and Reading |
| 2693–2699 | 1948 | Post-World War II additional units |
| 2700 | 1955 | Accident replacement unit |
The handful of post-war units were of completely different appearance, of all-steel construction, and looked very like the standard 4-SUB units being built at the same time, with flat ends, whereas the main 2-HAL units had the domed end appearance of the first 10 prototype "Queen Mary" 4-SUB units.
In the early 1960s the Eastern Division was fully changed over to EP-braked electric stock, and the 2-HAL units operating from Victoria to Maidstone/Gillingham etc. were removed to the Central and Western Divisions, being replaced by the large new build of 2-HAP units. The units then remained in service on these divisions until replaced at the end of their life by new 4-VEP units.
