The Class 158 "Super Sprinter" was built be BREL
between 1998 and 1992 to replace many locomotive-hauled passenger trains, and
allowed cascading of existing Sprinter units to replace elderly first generation
DMUs. They were described as' key long-distance cross-country routes".
A total of 182 units were built, mainly as two-car units. 17 units were built as
three-car units; eight of which have since had the centre car transferred to
different units of the class, whilst another eight have been upgraded to be Class 159s.
Currently South Western Railway operates Class 158 units 158880-888 and 890
from Exeter St Davids to Waterloo and on the Salisbury to Romsey via Southampton
Central service. South Western Railway also operates the Class 159 units that
were converted from Class 158 units 8 and 890. N°158885 was fitted with a
ZF fuel saving transmission instead of the usual Voith T211rz or T211rzz
hydraulic, but this was ultimately unsuccessful and the unit had reverted to the
original arrangement by March 2017. Originally brought in to replace South West
Trains class 170 fleet, SWT's class 158s saw a brief use on the former
Reading to Brighton service, before the service was truncated at both ends
within the new South Western franchise of 2007.
