The Temperature of Rolling Stock
Rolling stock covers any type of self-propelled vehicle that carries passengers, cargo, or both. It also covers personnel carriers such as trains, trams, buses, trolleys, streetcars — even cable cars. More recently, this term has been used to include automated guided vehicles like cars and Forklifts, as well as hovercraft.
Temperature is a major factor in the safe operation of rolling stock. The level of temperature must be controlled in terms of both its range and consistency, as well as in regular monthly maintenance. Failure to do this can cause serious problems in terms of maintenance costs and even passenger safety.
The temperature of rolling stock should be normally maintained between about 40 and 60 degrees Celsius for safety and performance reasons. When temperatures exceed this range, the locomotives and other components can start to suffer failures and breakdowns. For example, excessive heat can cause the brakes to malfunction, the axle bearings to be damaged, or even the axle plates themselves to warp.
In terms of regular maintenance, it is essential to check the temperature of rolling stock before and after use. The fluctuation of temperatures over time is a major factor in its lifespan as an operating unit. In extreme cases, high temperatures can also present a fire risk if there are combustible materials aboard. Therefore, it is important to monitor the temperature of rolling stock and take appropriate action if required.
In some instances, where there is a risk of significant heat disturbances, precautions must be taken. Cooling systems can be installed on rolling stock to help maintain the correct temperature levels, while the components must also be checked and adjusted as appropriate to avoid failure.
In summary, the temperature of rolling stock is important for its safe operation, consistent performance, and regular maintenance. It is essential to check the temperature regularly and make adjustments when necessary. If extreme temperatures are experienced, additional cooling systems may have to be installed to protect the components and passengers.
