Operator: Bradford C.T. Chassis: AEC 661T Body: English Electric H32/28R New: 1934
Additional information: A rear view of the lower deck framing on the chassis. These bodies were to prove troublesome in service and my suspicion is that welding the waistrail and other horizontal members in short sections between the pillars was the root of the problem. The fatigue loads on the welds would have been significant and embrittlement due to welding was probably not fully understood at the time. It is notable that later designs changed to a continuous waistrail rivetted to the pillar which was a technique adopted by the more successful steel-framed body builders.
