Question

A cross over is to be laid connecting two BG parallel tracks spaced 4.5 m apart.Assuming that 1 in 8.5 crossings are to be used, work out the various details required for setting the cross over.

Answer 1

Points and crossings should be inspected in detail, as the quality of a train ride greatly depends on their maintenance. The following important points should be checked.

Condition of tongue rails and stock rails There should be no wear on the top as

well as the gauge face side of the tongue rail. Badly worn out rails should be replaced. It should be ensured that the turnout side stock rail is provided with the requisite bend ahead of the toe of the switch; otherwise the alignment at this spot is bound to be kinky.
