Atkinson TRS3666 tractor can be operated with semitrailers from 31 to 34 ft in length, and at gross train weight of up to 36 ton; to obtain this versatility, tractor is designed with three axles, two of which are steered, and one of which is driven; either Cummins NH 220 or Rolls-Royce Eagle 220 six-cylinder diesel engine is available; both units have swept volume of 12,170 cc and power outputs are similar; Dunlop Pneuride air springs are controlled by leveling valve, which, by means of connecting link, responds to deflections of axle; to transfer load carried by second axle to driven one, valve that exhausts bellows is incorporated.
