Text Appearing Before Image: CONEMAUGH BRIDGE. Lincolnshire and Cambridge, it would be impossible to take theone class of roads above the other except by a constant series ofembankments, along which either the line or the road must pass.To overcome these difficulties, level crossings are provided, and Q 26 OUR IKON ROM is. attendants are put in charge of the gates. Such gates arc ofseveral kinds and sizes; sometimes four are employed; andsometimes it is considered that two large ones are sufficient.The sketch represents a pair of such as are commonly used onthe Great Northern Railway. They are massive, strengthenedwith iron, and hung on stout timbers deeply imbedded in theearth. They are twenty-six feet and a half in length, and costabout £$o. There are small wickets for foot-passengers. In themiddle of each gate is a large round board, painted red, bymeans of which an approaching train may see the gates closedacross the line. At night a red licdit is substituted. Text Appearing After Image: LEVEL CROSSINGS. In some instances safety gates for level-crossings have beenadopted. They can be opened by the movement of a hand-lever, connected with distance signals, and also with signals atthe crossing. By throwing the lever over, danger signals areraised, and the gates are unlocked and closed across the railway:the reverse operation frees the line and again locks the gatesupon the highroad. As it is impossible for the gates to beopened without the signals being simultaneously raised, and asthe latter cannot be released until the gates are again closedand locked, safety is ensured. One man can work both thesignals and gates. CHAPTER VIII.
