Derailment of a train comprising three empty six-wheel milk tank wagons marshalled next to the 2,500 hp Type 4 diesel-electric locomotive, and eight passenger coaches two of which were sleeping cars is described. It was travelling at about 60 mile/h. The rolling of the leading tank wagon as it approached Rothwell Haigh may have synchronized with the natural slight impact of the first common crossing, and its pattern could have matched the reversals in cant through the obtuse crossings, thus accentuating the roll. The tendency under the influence of the roll would be to lift and the falling cant gradient of the crossing was 1 in 93 for about 3 feet, it did so lift coming down on its next roll on the head of the rail at the point of derailment.
