This 'Flatrol' equipment carrier, of LNER design, was one of a total of nine from this lot.

Before acquisition it had had its cast steel tyres reprofiled to the British Rail BRP 1 profile.  It was disposed of by British Rail's Southern Civil Engineers' department, being withdrawn from service in May 1978.  It has a capacity of 21.5 tons on a four-wheel trolley with baulks.  It had a British Rail TOPS code of ZVP.

It arrived at Quainton from Woking in April 1981, and departed for the Isle of Wight Steam Railway during 2006 as part of a transfer of Ivatt Trust vehicles to the Isle of Wight.
