British Rail Class 930

The British Rail Class 930 was reserved for former Southern Region electrical multiple units and diesel-electric multiple units converted for departmental use. Originally the series was reserved for de-icing and, later, sandite units. In recent years, however, other types have also been given numbers in this series. Electric and diesel units are dealt with separately

Electric units

The Southern Region initially numbered its departmental EMUs in a series between S1 and S101. In 1968, a new series was adopted; 001-099. Existing units were renumbered to fit in that series, which also included other non-passenger stock, i.e. those EMUs converted for parcels traffic. When TOPS class numbers were applied, these units mostly retained their existing numbers as the last three digits of their new TOPS class number. It should be noted that several of the numbers 001-099 have been reused for different units.

The table below lists all the units numbered in the Class 930 series, together with the sandite and de-icing stock used by the SR prior to the adoption of TOPS numbers.
