During the same year a second locomotive wasbuilt by Blackett for use on his line. In con-structing his machines, however, due regard wasnot paid to the weight of the rail on which theywere to run, and so it was found necessary tosubstitute for the four rigid wheels on which 24 RAILWAY EQUIPMENT. the machines were operated, two four-wheeledbogies.* This secured a more equitable divisionof the weight, while also permitting the machineto run around the sharp curves on the , when the road had been relaid withheavier rails, the four-wheeled bogies were re-moved and the engine again placed on four fixedwheels as in the first Middleton & Leeds Railway. 1812-13. Thirty cars were hauled iu a train. Up to this point in the introduction of thelocomotive, George Stephenson, who afterwarddeservedly became so prominent, had not ap-peared prominently as an inventor or con-structor. His attention, however, had been * I use the term bogie in reference to the English customrather than that of America. In England a four-wheeled truckwith the bogie principle is called a bogie, but in the UnitedStates only two wheels are recognized as coming under thishead. The English were slow to utilize or introduce the two-wheeled bogie. From time immemorial the rigid wheel-basewas the fashion in that country. This prevented the sharpcurves which are so common in America and which so greatlylessen the cost of railways. The railways in Great Britainhave been constructed with a view to the avoidance of suchcurves, while the financial necessities of the American roadsrendered them
