The Southern Railway (SR) gave the designation 2-HAL to the electric multiple-unit passenger trains built during the late 1930s to work long-distance semi-fast services on the newly electrified lines from London Victoria to Maidstone and Gillingham (Kent). This type of unit survived long enough in British Rail ownership to be allocated TOPS Class 402.
