What are the train guard rails called?
When travelling on a train, you may have noticed a series of metal fences that run along the sides of the tracks. These are known as guard rails, or sometimes safety fences. They are installed for a very important reason - to prevent derailments in the event of an accident.
The guard rails work by guiding the wheels of the train inwards towards the centre of the track. This helps to keep the train on the rails, even if it is travelling at high speeds. In addition, the rails also help to prevent the wheels from bouncing out of the track, which can cause serious damage to the train and the track itself.
What are the different types of guard rails?
There are several different types of guard rails that are commonly used on railway tracks. The most common type is the flange guard rail. This is a low fence that is located between the rail and the sleepers, and it is designed to prevent the wheels of the train from lifting off the rails.
Another type of guard rail that is widely used is the safety guard rail. This type of rail is designed to provide additional protection in the event of an accident. It is usually higher than the flange guard rail, and is located on the outside of the track.
Yet another type of guard rail is the bullnose guard rail. This type of rail is designed to absorb the impact of a derailment, and prevent the train from overturning. It is usually made from reinforced concrete, and it is installed at the end of a track to protect against collisions.
How do guard rails work?
Guard rails work by providing a physical barrier between the train and the surrounding environment. They are usually made from steel or concrete, and they are designed to be strong enough to withstand the forces that are generated by a train travelling at high speeds.
In addition, guard rails also help to guide the wheels of the train inwards towards the centre of the track. This helps to keep the wheels in contact with the rails, even in the event of an accident. In addition, the guard rails also help to prevent the wheels from bouncing out of the track, which can cause serious damage to the train and the track itself.
What are some of the benefits of guard rails?
There are many benefits to using guard rails on railway tracks. Perhaps the most important benefit is that they help to prevent derailments. By guiding the wheels of the train inwards towards the centre of the track, the rails help to keep the train on the rails even at high speeds.
In addition, guard rails also help to prevent accidents and collisions. By providing a physical barrier between the train and the surrounding environment, they help to reduce the risk of accidents that can be caused by cars, pedestrians, and other objects that may be present near the tracks.
Finally, guard rails also help to protect the track itself. By preventing the wheels of the train from bouncing out of the track, they help to reduce the risk of damage to the track and the surrounding infrastructure.
What are some of the challenges of using guard rails?
Despite their many benefits, there are also some challenges associated with using guard rails on railway tracks. Perhaps the most significant challenge is cost. Guard rails can be expensive to install and maintain, and this cost can be a significant barrier for operators who are looking to improve safety on their networks.
In addition, guard rails can also be a source of friction between the train and the track. This friction can cause wear and tear on both the train and the track, which can lead to increased maintenance costs over time.
Another challenge associated with guard rails is the potential for derailments in extreme weather conditions. Heavy rain, snow, and ice can all create conditions that make it more difficult for the wheels of the train to stay on the rails, and this can increase the risk of derailments.
In conclusion
Guard rails are an important safety feature that are used on railway tracks around the world. They help to prevent derailments, accidents and collisions, and they also protect the track and the surrounding infrastructure. While there are some challenges associated with using guard rails, the benefits far outweigh the costs, and they are an essential component of any modern railway network.
