t the moment of collision, an up empty (L.M. & S.R.) unfitted freight (3) was travelling in a northerly direction at a speed of about 20 to 25 m.p.h. The engine and about twelve wagons had passed clear of an overbridge north of Charfield Station. A down semi-fitted (G.W.R.) freight train (2) was being slowly propelled off the down main line in a northerly direction into a down lie-by siding. With the exception of all but two of the wagons and the engine and tender, this train had passed clear of the fouling point of the siding with the down main line, the engine at the moment of the collision being under the overbridge. The 10 pm. (Leeds to Bristol) down mail passenger train (1), travelling at high speed in a southerly direction, grazed the two wagons of the Great Western freight train, and struck the right-hand back end of the tender of the engine of that train, with the result that the engine of the mail train was derailed towards the six-foot, and came into contact with the empty wagons of the L.M. & S.R. up train. The mail train engine drove its way under the bridge past the Great Western engine, and through seven or eight wagons of train (3), and finally overturned on its right side, coming to rest leaning against the up side slope of the cutting about 25 ft. clear of the south face of the overbridge. The Great Western tender was overturned on to its left (east) side against the northern abutment wing wall of the bridge. The tender of the mail engine, and the Great Western engine which became wedged under the bridge against the eastern abutment wall, together with the wreckage of the destroyed wagons of train (3), blocked the forward movement of the coaching stock behind the mail engine. The result was that the first vehicles piled themselves on each side of, but chiefly under, the bridge in an extricable mass of steelwork and timber wreckage.
