Abstract
Equilateral switch is switch with all elements are arranged symmetrically relative to the axis of the main path. Equilateral switches are widely used in marshalling-yard bays stations, because they work in cramped conditions. Equilateral switch sometimes used when it is necessary to achieve higher speeds on both side of the track. For example, the symmetric transfer switch type R65 frog number 1/11 of the speed limit in the lateral direction 1,75 times greater than for an ordinary switch of the same brand and type. Equilateral switch or applied straight, or with curved blades. Straight tongue to main station track of industrial transport. On the main paths in symmetric switches used curved tongues. In educational and reference literature very briefly presents data on the methodological calculations and design features of symmetric switches for different operational conditions, including for the mainline and industrial transport. This article summarizes some of the developments to remedy this drawback of textbooks.
