Why do train tracks have sleepers?
First you've got the rails – these are the long metal strips on which the train wheels run. Because they're metal, they can be affected by changes in temperature, which can cause them to expand and contract. Sleepers are the horizontal supports which lie underneath the rails, helping hold them in place.
Why do rails buckle in UK?
When Britain enjoys a summer heatwave, rails in direct sunshine can be as much as 20°C hotter than air temperature. Because rails are made from steel, they expand as they get hotter, and can start to curve this is known as 'buckling'.
Why is there wood between rails?
Wood has the natural flexibility that is perfectly suited for the loads running on railroad tracks every day. Wood ties are engineered to perform under heavy load conditions. The durability of the wood tie means lower costs for railroads.
What is a railroad beam called?

Why are there no gaps between railway tracks?
Gapless railroads have their joints welded together to reduce noise. The lack of a gap between rail sections also reduces wear on both the track and the wheels. However, because the weld essentially produces one very long track, the individual sections have no room to expand as they get warm on hot days.
What are the bars on train tracks called?

Do train tracks wear out?
But like any piece of machinery, rail tracks can wear down and become damaged over time.
Why are train tracks white?
We paint certain parts of the rail white so they absorb less heat – and expand less. Typically, a rail painted white is 5°C to 10°C cooler than one left unpainted.
