Concrete sleeper Wikipedia

Interest in concrete railway sleepers increased after World War II following advances in the design, quality and production of pre-stressed concrete. Chaired bullhead concrete sleepers have been around since at least the 1940s; the Great Western using a two-holed chair, thus saving both scarce wartime timber and steel fixing bolts. [4]

Concrete Sleeper an overview ScienceDirect Topics

The sound radiation from an individual sleeper can be considered as that from a flat rectangular surface located in a plane baffle. Its lower surface is hidden by the ballast and can therefore be neglected. Sleepers are typically 2.5 m long and 0.2 to 0.25 m wide. The vibration of concrete sleepers has been described in Section 3.7.

Dec 21, 2018 A breakthrough for the use of the concrete sleeper was the development of pre-stressed concrete in the 1930s and 1940s. This design compensated for the low tensile strength of the concrete and met technical requirements in an economical way. Thus, in 1940 the first pre-stressed concrete sleepers for the Deutsche Reichsbahn were manufactured by
