 This process was completed in 2016.The original 30 ex-Class 458/0 units are numbered 458501-458530, and are distinguishable from the ex-Class 460 stock (458531-458536) by noting the different ribbon-glazed windows on ex-Class 460 units, different door window sizes and the lack of a pantograph recess on ex-Class 460 units.This means that if future conversion to OHLE is required for this fleet, the process will be much simpler on 458501-458530 than 458531-458536.
