Transport for London is seeking a supplier for the overhaul of the S&B wagons which are essential to meet the maintenance regime. The scope involves a comprehensive overhaul of all S&B wagons encompassing brake equipment, drawgear, bogies, bodywork, fittings, gauging and brake performance checks, as well as any repair works arising from the condition assessment undertaken during the overhaul process.

Works must be performed using approved methods and by personnel with demonstrated competence in maintaining specialist rail vehicles. The fleet consists of 52 wagons which were procured in 1996.
