 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 appearence, 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 appearence 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.

The original formations of these units are set out in the table below:
