Sleeper Density in Railways with solved example

Sleeper Density in Railways

Number of sleepers provided for one rail length of track is called sleeper density. If “N” is the length of one rail in meters,

Sleeper Density = N+ X , (X –> 3 to 6)

For a Broad Gauge track, total number of sleepers required for 1km length of railway track if sleeper density = N+5

Length of one rail = 12.8m =13m

Sleeper Density = N+5 = 13+ 5 = 18

Total number of sleepers required for 1km length = (18/12.8)x1000 = 1406 sleepers.
