Spring crossings
In all normal crossings the wheels have to negotiate a gap in the continuity of running rail while going on the straight or in turn out direction. With the use of spring crossing the gap in the straight direction can be avoided. In such a crossing one wing rail is moveable and is held against the vee of the crossing with a strong spring. When vehicles pass over to main track, there is no gap to be negotiated at the crossing nose. In the case of vehicles moving on the turn out track, the sliding wing is forced out by the wheel flange and the movement beyond the wing is no different than no normal crossing.

| Spring crossing |
Spring crossing are of great advantage at location where bulk of the traffic passes over the straight road and only little slow traffic on the turn out side. Such locations are emergency crossovers on double line at way side stations and slip siding points.
