- Diamond crossings not to be flatter than 1 in 8.5
- Note: Diamond crossings as flat as 1 in 10 will usually be sanctioned if recommended by the Commissioner of
Railway Safety.
- Minimum length of tongue rail 3660 mm
- Minimum length of train protection, point locking or fouling treadle bar 12800 mm
Important Points
Points and crossings:
- Maximum clearance of check rail opposite nose of crossing 48 mm
- Note: In case of turnouts laid with 1673 mm gauge, the clearance shall be 45mm instead of 48mm.
- Minimum clearance of check rail opposite nose of crossing 44 mm
- Note: In case of turnouts laid with 1673mm gauge, the clearance shall be 41 mm instead of 44 mm
- Maximum clearance of wing rail at nose of crossing 48 mm
- Note: In case of turnouts laid with 1673mm gauge, the clearance shall be 45 mm instead of 48mm
- Minimum clearance of wing rail at nose of crossing 44mm
- Note: In case of turnouts laid with 1673 mm gauge, the clearance shall be 41mm instead of 44 mm.
- Minimum clearance between toe of open switch and stock rail
- For existing works 95 mm
- For new works or alterations to existing works 115 mm
- The clearance can be increased upto 160mm in curved switches in order to obtain adequate clearance between
- gauge face of stock rail and back face of tongue rail.
- Minimum radius of curvature for slip points, turnouts 218 m (8 degree) or crossover roads
- Note: In special cases mentioned below this may be reduced to not less than the minimum of
- 213m radius in case of 1 in 8.5 BG turnouts with 6.4m overriding switch, and
- 175m radius in case of 1 in 8.5 scissors crossing to allow for sufficient straight over the diamondcrossing between crossovers.
- Minimum angle of crossing (ordinary) 1 in 16
- Note: Crossings as flat as 1 in 20 will usually be sanctioned if recommended by the Commissioner of Railway
