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.

[ permanent dead link] Severn Beach and Avonmouth to Bristol Temple Meads and Weston-super-Mare (The Severn Beach line) (PDF, 449 KB) Historically, steel ties have suffered from poor design and increased traffic loads over their normally long service life. These aged and often obsolete designs limited load and speed capacity but can still be found in many locations globally and performing adequately despite decades of service. There are great numbers of steel ties with over 50 years of service and in some cases they can and have been rehabilitated and continue to perform well. Steel ties were also used in specialty situations, such as the Hejaz Railway in the Arabian Peninsula where the dry, hot climate made wood ties unsatisfactory. [9] Historically wooden rail ties were made by hewing with an axe, called axe ties, or sawn to achieve at least two flat sides.

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. Length Most European railways also now use concrete bearers in switches and crossing layouts due to the longer life and lower cost of concrete bearers compared to timber, which is increasingly difficult and expensive to source in sufficient quantities and quality.

The 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. Crossties. Paterson, New Jersey: Railway Tie Association. March–April 2010. ISSN 0097-4536.
