The L.N.E.R. laid a system of switch-and-crossing work in flat-bottom rail in 1944, for experimental purposes. The turnout, which used 110-lb. flat bottom rails, is illustrated. The normal 1 in 20 rail cant or tilt is retained through the connections, and heel-less switches are used; the lifting of the switch above the stock rail has been eliminated. In general the switch angles, radium of switch curve, and the top planing are similar to bull head British Standard design. The usual type of fastening used in this flat-bottom switch and crossing work is the hook bolt and malleable iron clip to secure the rail to the cast-iron base plates, and chair screws to fasten these plates to the timbers.
