Perspective construction of hump necks

Abstract

The article analyzes the problems faced by designers when developing hump necks with a large number of sorting paths. For last paths, it is very difficult to fit curves with a radius of 200 meters or more. It is necessary to use reverse curves, which creates additional resistance to the movement of wagons when rolling down the sorting hump. New designs of hump necks with ten-track bundles were proposed, allowing to easily enter curves with a radius of 200 meters or more. Besides, the proposed hump necks provide the required width of the interstices. The design of the hump neck also affects the longitudinal profile of the descent part. Due to the fact that the section of the switch area turns out to be longer compared to the classic eight-track beams, the high-speed section turns out to be shorter. This makes it possible to design the high-speed sections steeper, resulting in earlier separation of the detachments on the switches and retarders. The article concludes that the main parameters of the sorting hump with a six- and four-track bunches differ insignificantly. The lengths of the calculated paths are almost the same. The number of switches along the rolling route remains unchanged. The few disadvantages include the fact that the angle of rotation of the last path curve increases slightly as compared to the classic version. However, the required number of retarders on the descent part of the hump is reduced. This significantly reduces the amount of investment in the construction of a sorting hump.
