A NEW design of single-deck bus is being purchased by the Belfast Ulsterhus concern in its 1975/76 bus replacement programme. A total of 170 vehicles are being purchased for use on city centre and suburban services. The vehicles have Bristol RELL chassis with Gardener 6HLX and 6HLXB engines and a new design of body built by Walter Alexander Ltd at Mallusk near Belfast. Allthe buses are designed for one-man operation, and in the city centre vehicles provision for 74 passengers has been possible. A special feature of the body is the forced ventilation system. Fresh air is drawn in at vents at the front of the body and is distributed along the full length of the vehicle through ducts above each window. Passenger-controlled vents are provided above each seat,
