The need for gaps in railway lines
There are several reasons why gaps are necessary in railway lines. Some of the main reasons include:
1. Expansion and contraction: Railway tracks are made of metal, which can expand and contract with changes in temperature. Gaps in the tracks allow for this thermal expansion and contraction without causing damage to the tracks.
2. Drainage: Gaps in the tracks allow for proper drainage of water, preventing water accumulation on the tracks which can lead to deterioration and safety hazards.
3. Movement of trains: Gaps in the tracks allow for the smooth movement of trains, as they provide flexibility and movement in the tracks which helps in absorption of shocks and vibrations. This can help in reducing wear and tear on the tracks and increase the overall lifespan of the railway line.
4. Maintenance: Gaps in the tracks also allow for easier maintenance of the tracks, as they provide access points for inspection and repairs.
Overall, gaps in railway lines play a crucial role in ensuring the safety, durability, and efficiency of railway tracks.
