In the modified Childs-Latimer rerailing guard, inclined blocks are fittedinside and outside the track rails at the abutment, where the guard railsbegin to converge. It is sometimes considered best to place such devices 50to 150 ft. from the bridge, so that if the wheels are too far out to be savedthe car will be wrecked on the approach and not on the structure.

These rails would be 30 ft. long, 8 or 10 ins. from the trackrails opposite the guard rail point, and flaring out to 4 ft. 8% ins. from piece of rail 15 ft. long should extend from the inner ends of these guardstowards the bridge (being parallel with the track rails), and a rerailingdevice may be set between them and the track rails. Flaring guard tim-bers at bridge approaches or entrances should be laid on long ties firmlybedded and tamped in good ballast for their entire length. In some cases,bumper posts are placed on the approach in line with the bridge trusses, sothat a derailed car far enough off the track to strike the truss would haveits trucks stripped from under it before reaching the structure.
