Railway Sleeper Replacement Project

How many sleepers per rail length are required for the railway sleeper replacement project?

What is the total number of sleepers that need to be replaced in the 100km section?

Sleeper Density Calculation

For heavy-duty railways, the common estimate is around 15 to 20 sleepers per rail length. With a total length of 100km, we can calculate the number of sleepers needed for replacement:

Using the formula: Total number of sleepers = Total length / Sleepers per rail length

100km / 15 = 6666.67 sleepers (approx. 6670 sleepers)

If we have 100,000 sleepers in healthy condition, we can determine the number of damaged sleepers to be replaced:

Number of damaged sleepers = 100,000 - 6670 = 33,300 sleepers

Therefore, we need to replace 33,300 damaged sleepers in this 100km section of the railway track.
