The stretcher bars (In this case of flat construction) link the two turnout blades together so that they can operated as a pair. On the nearest stretcher bar on the right hand end you can see the connection hole to connect the blades to the operating mechanism. 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. Schut, Jan H. (2004). "They've Been Working on the Railroad". Plastics Technology.

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.

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.

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. Krylov, Victor V. (2001).

One common manufacturing process for railroad ties is sawing. This involves cutting the logs into the desired dimensions using large saw blades. The dimensions can be customized according to specific requirements, such as length, width, and height. Influence of Sleeper Type on Train Emission" (PDF). European Acoustics Association (E.A.A.), Hellenic Institute of Acoustics (HEL.IN.A.) . Retrieved 2022-03-12. 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.
