The 6H50 is one of those workings that appears regularly in the WTT but rarely actually runs. However, the 13.16 Willesden to Tunstead did run on this day with 66616 leading the train. It passes through Roade cutting with a largely empty set of JYA wagons apart from four that were mysteriously fully loaded at the rear. This particular Freightliner 66/6 is far better suited to this sort of working with its lower gearing and consequentially greater torque (tractive effort in railway parlance) but reduced speed - sixty-five as opposed to seventy-five miles per hour compared to a standard Class 66. Last week, this locomotive was seconded to an intermodal service due to a failure and is the only time that I can recall seeing a 66/6 working such a train, see.....
