Number of Rails per km at given Number of Sleepers per km Solution

STEP 0: Pre-Calculation Summary

Formula Used

Number of Rails per Km = 2*(Number of Sleepers per Km)/(Length of Single Rail+Density Factor)
N = 2*(N_s)/(L+x)
This formula uses 4 Variables

Variables Used

Number of Rails per Km - Number of Rails per Km is the total number of rails in one kilometer or 1000m.
Number of Sleepers per Km - Number of Sleepers per Km is the total number of sleepers required in one km.
Length of Single Rail - (Measured in Meter) - Length of Single Rail Indian Railways has standardized a rail length of 13 m (previously 12.8 m) for broad gauge and 12 m (previously 11.8 m) for MG and NG tracks.
Density Factor - Density Factor is any number which when added to a length of rail, will give sleeper Density. In India x-4, 5, 6 or 7 is used for main-tracks.

STEP 1: Convert Input(s) to Base Unit

Number of Sleepers per Km: 1463 --> No Conversion Required
Length of Single Rail: 13 Meter --> 13 Meter No Conversion Required
Density Factor: 6 --> No Conversion Required

Number of Rails per km at given Number of Sleepers per km Formula

Number of Rails per Km = 2*(Number of Sleepers per Km)/(Length of Single Rail+Density Factor)
N = 2*(N_s)/(L+x)

What is the function of sleepers?

The primary function of a sleeper is to grip the rail to gauge and to distribute the rail loads to ballast with acceptable induced pressure. The side functions of a sleeper include the avoidance of both longitudinal and lateral track movement. It also helps to enhance correct line and level of the rails.
