Steam Engine Trains Tie

Product Information

In Europe, the standards for railroad tie dimensions may vary slightly from country to country. However, there are general guidelines that ensure consistency and compatibility within the European railway network. European railroad ties are typically longer than their North American counterparts, with a standard length ranging from 8 to 9 feet. This additional length allows for greater stability and load-bearing capacity, especially on high-speed rail lines. The fractional inch spacing at the fishplate corresponds to the thermal expansion gap allowed between the rail ends. Crossties. Paterson, New Jersey: Railway Tie Association. March–April 2010.

Additionally, some manufacturers utilize pressure treatment processes to enhance the durability and longevity of the ties. This involves injecting preservatives into the wood under high pressure, which not only protects against decay and insect infestation but also helps maintain the dimensions over time. The width of a railroad tie is another crucial dimension that affects its performance and compatibility. Standard width for railroad ties typically ranges from 8 to 10 inches, or 20 to 25 centimeters. This width provides a stable base for the rails to rest upon and helps distribute the weight of the trains evenly. Wide sleepers: so far, so good!". railone.com.

Another technique used is planing, where the ties are passed through a planing machine to achieve a smooth and uniform surface. This process helps ensure consistency in dimensions and improves the overall appearance of the ties. On the highest categories of line in the UK (those with the highest speeds and tonnages), pre-stressed concrete ties are the only ones permitted by Network Rail standards.

When it comes to railroad ties, or sleepers as they are also known, there are certain standard dimensions that are followed for consistency and compatibility within the railway industry. These dimensions include the length, width, and height of the ties. Let’s take a closer look at each of these dimensions and their significance. LengthThe manufacturing processes employed in the production of railroad ties also have a significant influence on their dimensions. Different techniques and machinery can result in variations in size and shape. A recent example of using bow tie analysis as part of a Taking Safe Decisionsprocess was a cross-industry investigation of concerns over freight derailment. The development of the bow tie brought together several disciplines, and representatives of different stakeholder companies. The freight derailment bow tie model supports the activities to manage freight risk under the rail industry’s health and safety strategy Leading Health and Safety on Britain's Railway.
