BRITISH RAIL CLASS 204

The British Rail 'Class 204' designation has been used twice for two different types of diesel-electric multiple units.
The original units, numbered in the range 1119-1122, were two-car versions of the Class 205 '3H' units, and were classified as 2H under the old system. Three of the four units were reformed in 1979 with the addition of centre trailers, and thus were reclassified as Class 205 (or 3H). The fourth unit was converted into a 3T set (see below).
In 1979, four units were converted from Class 205 units, by reforming the ex-2EPB driving trailers from redundant Class 206 units. These new units, also classified as 3T, were renumbered into the range 1401-1404. In 1986, the units were renumbered to 204001-004 to conform with the TOPS numbering system.
