rälsfot

Rälsfot is a Swedish term that translates to "rail foot" or "flange" in English. It refers to the lower, horizontal part of a railway rail. This section of the rail is designed to rest on the sleeper, also known as a tie, and it provides a stable base for the entire track structure. The width and shape of the rälsfot are crucial for distributing the load from passing trains to the underlying ballast and subgrade, preventing excessive settlement and ensuring track stability.

The rälsfot is integral to the overall design of a railway rail, working in conjunction with the web and the head of the rail. The web connects the foot to the head, providing vertical strength and resistance to bending. The head, which is the uppermost part of the rail, is the surface on which the train wheels roll. The robust construction of the rälsfot contributes significantly to the rail's ability to withstand the immense pressures and stresses encountered in railway operations. Its design also facilitates efficient manufacturing and installation processes.
