Bell crank levers are usedinstead of pulle^-s where the wire changes the draws at Cleveland the operating lever is put atthe edge of the draw, so that the conductor is in dangerof falling into the river if he tries to open the switchwhen the draw is open This plan comes very nearbeing an absolute protection against a car going througha draw. For a bumper at the end of a derailing switchthe rails are bent up, and a rail bolted across the endsthree feet from the ground. The plan of overheadconnection is specially valuable on drawbridge
