As a railway infrastructure expert, I have spent years studying the dynamics and maintenance of rail tracks. One of the critical factors in ensuring the longevity and safety of rail systems is understanding and managing the effects of thermal expansion and contraction. The presence of gaps in railway tracks is a deliberate design choice, and it plays a vital role in the overall integrity and functionality of the track system.
Rail tracks are subjected to a variety of environmental conditions, with temperature fluctuations being one of the most significant. As the temperature rises, the steel in the rails expands, and as it cools, it contracts. This phenomenon is known as thermal expansion. Without the proper accommodation for this expansion, the rails would be under immense stress, which could lead to buckling, warping, or even catastrophic failure.
The gaps in the tracks, often referred to as expansion joints, are engineered to allow for this natural expansion and contraction. They provide a buffer zone that prevents the rails from coming into direct contact with each other when they expand due to heat. This is particularly important for longer sections of continuous rail, where the cumulative effect of thermal expansion can be substantial.
If these gaps were not present, the rails would have no choice but to push against each other as they expand. This could result in a buildup of enormous stress within the rail structure. Over time, this stress could lead to deformation, cracks, and potentially even derailments, posing a significant risk to both the infrastructure and the safety of passengers and cargo.
Moreover, the design of these gaps also takes into account the material properties of the rails. Steel, being the primary material used in rail construction, has a specific coefficient of thermal expansion. This means that for every degree of temperature change, the steel will expand or contract by a predictable amount. Engineers must calculate the necessary size of these gaps based on the expected range of temperature fluctuations in the region where the track is laid.
In addition to thermal considerations, the gaps also serve other purposes. They can help to absorb vibrations and reduce noise, contributing to a smoother and quieter ride for trains. They also allow for easier maintenance and inspection of the tracks, as they provide access points where workers can check for wear, damage, or other issues.
It's also worth noting that the management of these gaps is an ongoing process. As the rails wear and the environment changes, the size and condition of the gaps may need to be adjusted. This requires regular monitoring and maintenance to ensure that the gaps continue to serve their purpose effectively.
In conclusion, the gaps in railway tracks are a critical component of rail infrastructure design. They are there to accommodate the natural thermal expansion and contraction of the rails, thereby preventing the buildup of stress that could lead to damage or failure. By understanding and properly managing these gaps, we can ensure the continued safety, reliability, and efficiency of our rail systems.

So that there is enough margin for the tracks to expand and contract due to the temperature changes. If that gap is not left then the tracks might have enormous stress in them while expanding due to heat. ... Thermal expansion of long continuous sections of rail tracks is the driving force for rail buckling.
