Standard Railroad Tie Dimensions It is possible to develop a bow tie following an incident or accident, to understand what actually happened, why things went wrong, and where there might be weaknesses in the safety management or set of controls that we can learn from.We include services from other train companies where they cover part or all of our route, except where shown, and in all cases, timetable information is available in both directions.

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 Taylor, H.P. (August 17, 1993). "The railway sleeper: 50 years of pretensions, prestressed concrete". The Structural Engineer. Institution of Structural Engineers. 71 (16): 281–288. 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.

Various methods exist for fixing the rail to the railroad ties. Historically spikes gave way to cast iron chairs fixed to the tie, more recently springs (such as Pandrol clips) are used to fix the rail to the tie chair. Most services across the country stop between around 01:00 and 05:00 each morning to let the trains have a nap, so it's usually fairly easy to search for the first train of the day using our tool – simply type in your departure (from) and arrival (to) stations and choose a time inside of this morning window.

Bristol Temple Meads to Severn Beach, Filton Abbey Wood, Patchway, Bristol Parkway and Yate (stopping services) (PDF, 452 KB) The fractional inch spacing at the fishplate corresponds to the thermal expansion gap allowed between the rail ends. Another example might be their use in understanding an emerging new risk, such as Covid-19 infection of passengers using the trains. This could be used to shape, and direct discussions as new information develops and understanding improves. When connected to the rodding, moving them to one side or the other relaxes the flexing in one blade, while increasing the flexing in the other. So the forces needed are cancelled out, and they can be moved across easily. This is what is meant by springing the blades against each other.

Webb, David A.; Webb, Geoffrey V. Gauntt, James C. (ed.). "The Tie Guide" (PDF). www.rta.org. Railway Tie Association. p.59 . Retrieved February 18, 2019. Moisture content is another significant factor that affects railroad tie dimensions. Wood is a hygroscopic material, meaning it absorbs or releases moisture from its surroundings, leading to swelling or shrinking effects. The crosstie spacing of mainline railroad is approximately 19 to 19.5 inches (48 to 50cm) for wood ties or 24 inches (61cm) for concrete ties. The number of ties is 3,250 wooden crossties per mile (2,019 ties/km, or 40 ties per 65 feet) for wood ties or 2,640 ties per mile for concrete ties.

Severn Beach and Avonmouth to Bristol Temple Meads and Weston-super-Mare (The Severn Beach line) (PDF, 449 KB) For example, oak and pine are commonly used wood species for railroad ties. Oak is known for its durability and strength, making it ideal for heavy-duty applications. On the other hand, pine is more affordable and widely available, making it a popular choice for lighter loads.
