Every bus operator has to have 'utility' vehicles and Southdown Motor Services were no different. Over the years they employed cut-down buses to act as breakdown trucks, open toppers as tree cutting vehicles and double decker's as driver trainers. There were also left luggage offices, waiting rooms and so on.nnDuring the NBC years a uniform yellow or yellow and white livery was applied to such vehicles although in the earlier years of the period, they were often the last vehicles to be painted.n
