In India the rails are manufactured by Open hearth process Duplex process Neither Open hearth process nor Duplex process Both Open hearth process and Duplex process 29. Flat mild steel bearing plates are used With wooden sleepers at locations where creep is likely to be developed For points and crossings in the lead portion On all joints and curves On All of the options 30. The rail is designated by its Weight Cross-section Length Weight per unit length 31.

For providing the required tilt of rails, adazing of wooden sleepers, is done for Double headed rails Bull headed rails Flat footed rails Any type of rails 35. To avoid the damage of nose of crossing, the wing rails are ramped so that nose of crossing remains at a lower level by 4 mm 6 mm 5 mm 3 mm 36. On Indian Railways, number of a crossing is defined as Contingent of angle of crossing Cosine of angle of crossing Sine of angle of crossing Tangent of angle of crossing 37.
