The Rail Tracks for Trains to Operate Along
Trains are a very resourceful type of transportation that move thousands of tons of materials annually. There are also trains that transport people to various locations for business or leisurely travel. This is all possible with the use of rail tracks that guide the train along the determined route. In order to ensure a smooth ride for the train as well as one that is safe for the passengers, ballast is laid which looks like gravel. Some people think this is used to give it a nice look because it is a shade of light pink, but the ballast serves a useful purpose. It allows water to drain from snow and rain to keep it off the tracks.
Railroad ties are placed on top of the ballast which look like long wooden planks. They go across the train tracks in the opposite direction of the rails. This helps to keep the rails in place properly so that there isn’t any risk of the trains being pushed off the rails due to inaccurate alignment. The rails can contract and expand due to the weather and the ties help them maintain their shape. Many railways are switching from wooden ties to those made out of concrete.
The wood is known to rot out and this means a great deal of time has to be spent repairing them. Even though the concrete ties are more expensive than those made from wood, they don’t have to be replaced very often so it does save money in the long run. It is believed that these concrete ties provide the train with a smoother ride and that protects the freight as well as keeps all of the train cars in good working condition. They are heavier than the wooden ties though so it takes longer to get them in place. It also requires heavy duty devices to secure them in place that won’t break the concrete. The rails must be placed the exact width from each other necessary in order for the train to be guided along them. They are made from a very heavy type of steel and held in place with long spikes. The steal has to be heavy in order to be able to hold up to the heavy weight of the loads the train carries. Many railway companies invest in welded track because this allows them to place more weight on the rails with less damage. In the long run it will cost them less in repairs and maintenance.
In many instances these welded tracks also allow for the trains to move along at a faster speed. Switches in the rail tracks allow for a train to move from one set of tracks to another. They are commonly used as a type of bypass when you have two trains on the same stretch of track but heading different directions. The switch allows one train to go around the other while the other continues in the normal path. This type of rail design allows several trains to be on the same tracks at the same time. It is important for switches to work properly or the risk of two trains crashing into each other is possible. Some areas of the train tracks feature built in signals that activate the safety signals at the upcoming railroad crossings. These areas of the track are insulated to help prevent any malfunctions in the signals. When cars are ready to cross the railroad tracks it is these signals that will prevent them from going across when it isn’t safe. It is vital to the railway industry that the tracks are always ready to for trains to safely move across them.
Regular inspections of each section of the tracks helps to ensure this process. Various railroad companies have gangs that work to offer regular maintenance for the train tracks and to take care of any emergency repairs that need to be made. PPPPP Word Count 662 .
