Train services on single-track lines suffer from time losses due to crossings, imposed by the bidirectional traffic. The time losses, in this paper denoted crossing time, are caused by constraints in the infrastructure and delay propagation, which give a stochastic contribution that varies from one crossing situation to another.
Two examples of infrastructure improvements that decrease the crossing time are examined: partial double-track at the location of timetabled crossing and decreased inter-station distances. A mathematical model is used to evaluate these improvements.
Partial double-tracks seem to be very efficient when traffic intensity and delay variances are moderate. Shortened inter-station distances give less effect but are less sensitive to delay variance and give valuable additional line capacity.
The used model assumes independence between crossing trains, which imposes a moderate capacity utilisation. In more congested situations simulation methods are needed to make more complex crossing patterns possible.
