The Class 122s were built mainly for use on the
London Midland Region of British Railways, although some were also used in Scotland. They were used on a variety of lightly used lines, many of which were closed during the
Beeching Axe in the 1960s including the ex-
LSWR lines in West Devon and North Cornwall. Routes served included the
Stourbridge Town and
St Albans Abbey branch lines, as well as local services between
Dundee and
Arbroath. (The similar Pressed Steel Company built
Class 121 single units were also used on the Western Region). During the 1990s, refurbished Class 122 units were used on the Cornish branches between
Liskeard and Looe and
St Erth and St Ives. == Parcels conversion ==
