Class 159 Express Sprinter

The Class 159 is a sister class to the Class 158, indeed the twenty-two original sets were built as Class 158s but were converted at Babcock Rail for London Waterloo services to replace locomotive hauled trains to Exeter [1]. The conversion took place before their entry into traffic and the modifications included adding first class compartments and retention toilets. Eight more were converted from Class 158s in 2006-7 forming the 159/1 (the original 22 sets are 159/0).
