When it becomes hotter than the rails can stretch to more than the gaps between rails can handle, the rails start to bend becasuse they have expanded. If there is enough pressure to "pop out" tie spikes, the rail will bend. This is a bigger concern today because long section of rail, called Continuous Welded Rail (CWR) can be a quarter mile long and have no gaps to abosrb this expansion. This rail relies on "rail anchors" to hold the rail in place. However, under extreme conditions, the anchors start getting pushed off and this can result in a long section of track that has bent and can no longer carry a train.

Why do train tracks bend?
Train tracks are designed to have gentle curves in order to navigate the natural contours of the land, such as hills and valleys. Additionally, the curvature helps trains to maintain a comfortable and safe speed around corners without causing derailments. The slight bend in the tracks also assists with the distribution of weight and stress as trains pass over them.
Why do train tracks have stones under the rails?
these have small stones under them so that the rails will not bend, also when it rains these rails wont sink in the mud and the water will filter through them.
Why don't railway tracks bend when hot?
Railroad tracks can bend when they get hot. Train tracks have a small gap where one rail meets the next rail. These are called expansion joints. When it is hot the rails expand making the gap smaller, and when it is cold the rails contract making the joints wider. If the expansion joints are not wide enough and the rail gets hot enough it will expand more than the expansion joint can handle and the rails can buckle. In other situations the rails can get what are called sun kinks and the rails actually bend out of alignment.

Why do train tracks sit on rocks?
Train tracks sit on rocks, known as ballast, to provide stability and support to the tracks. The ballast allows for proper drainage and helps distribute the weight of the train evenly, preventing the tracks from shifting or sinking into the ground. Additionally, the ballast helps to reduce the impact of vibrations and noise produced by the passing trains.
Can curtain tracks bend?
Yes, some curtain tracks are designed to bend around corners or other obstacles. These flexible tracks can be bent to create curved or angled shapes for custom window treatments. It's important to check the specifications of the curtain track you're considering to ensure it can be bent as needed.
Why are wooden sleepers kept between railway tracks?
Well, honey, those wooden sleepers are there to support and secure the railway tracks. They help distribute the weight of the train and prevent the tracks from shifting or sinking into the ground. So, next time you're on a train, just remember those wooden sleepers are working hard to keep you on track.
Which one is an example of a difficulty caused by thermal expansion?
A common example of a difficulty caused by thermal expansion is when railroad tracks buckle in hot weather. The metal tracks expand due to high temperatures and may not have enough space to accommodate the increased length, causing them to bend and deform. This can lead to disruptions in train services and safety hazards.
