One hundred and seventy (172) two-car diesel multiple units of class 158/0 were built at BREL Derby during the period from 1989 to 1992. They can be found all across the UK railway network. The class 158/9 variant contained 3 cars from class 158/0 units. In essence a class 158/0 unit being broken in two with one half going to strengthen another class 158/0 unit.
On 22nd August 2006 class 158/9 diesel multiple unit No.158964 was at Worcester Foregate Street Station. The train is in the livery of Wessex Trains but by this time this was a First Great Western service. Photograph taken by Andrew Smith.
On 19th August 2010 First Great Western class 158/9 diesel multiple unit No.158956 consisting of car No.52748 (from No.158748) and all of No.158768 was photographed at Great Malvern Station. The unit had arrived from Brighton and after reversal at Malvern Wells formed the 14:51 from Great Malvern to Weymouth. Photograph taken by Andrew Smith.
This is also No.158956 but this time operating as a two-car class 158 diesel multiple unit (without No.52748) presumably because First Great Western was experiencing a temporary shortage of serviceable units. Photographed by Andrew Smith at Worcester Shrub Hill on 18th March 2011.
