ScotRail Trains Limited wish to overhaul the existing Knorr Bremse EP98 WSP control units on their fleet of 117 trailer cars and spares stock.

The WSP control units (Railway Cat number 064/012539) were installed in the mid-2000s, and are starting to suffer from failures related to leaking electrolytic capacitors, leading to damage to the PCB tracks and vias. The overhaul is expected to include the renewal of all electrolytic capacitors to be considered a minimum, but the following should also be considered: -Clean using a suitable method; -Renewal of other capacitors; -Renewal of relays; -Renewal of opto-isolators; -Functional testing on a suitable rig; -Soak testing; -Identification of overhaul (e.g. mod level plate, coloured stickers); -Any other ‘value add’ work considered worthwhile by the supplier.
