Determination of the work scope for removal of speed restrictions related to the track plan

Abstract

The greatest number of restrictions is related to the parameters and condition of curvilinear track sections. The technique for determination of cost of reorganization of curves at introduction of high-speed traffic for difficult sections of the track plan is developed. The law of work scope change depending on methods of the curve reorganization is established: expanding an existing track bed, adding a new track bed to existing one or shifting a track bed to a new route.
