Mcintosh built, atthe St. Rollos Works of the Caledonian Railway, some large4-6-0 inside cylindered engines designed for dealing withfast goods traffic In general, these engines follow the usualneat design of Caledonian engines, but an innovation wasmade in the design of the cab which has side windows similarto those used on the North Eastern and to a limited extent onthe Great Eastern line,-. These engines are fitted withRobinson flue tube superheaters and the cylinders are be-tween the frames and have their steam chests on the valves are used driven bv the ordinarv link motion by. Standard Boiler for 4-6-0 and 2-8-0 Type Great means of rockers. The leading coupled axle is the crankaxle and it is of the built-up description. Steam reversinggear is fitted. The boiler is of the ordinary type, having around topped outside fire box and direct roof stays, those infront close to the tube sheet being so arranged as to permit ofthe upward expansion of the inside fire box. Four 4-inchsafety valves are provided in common with all Caledonianengines of the larger type. The connecting rods have bigends of an unusual pattern, the ends of which are forked andthe brasses are held in position by means of a cap held bytwo large bolts.
