Abstract

The paper discusses technological drawbacks of dead-end passenger stations that decrease the capacity of a railway section in whole and constrain the possibility to decrease a minimal train-to-train interval. It is established that the main bottleneck of the dead-end station is the length of a yard neck. The authors present a method for calculation of a minimal acceptable train-to-train interval for lines with dead-end passenger stations that is determined by stational intervals of departure and arrival. The authors have analysed the international experience of elimination of capacity constraints and suggested measures and scheme solutions that allow increasing in various level the capacity of yard necks of dead-end passenger stations (construction of overbridge crossings, use of lock tracks, radical reduction of yard neck length with the use of high-speed switches, increase of speed).
