Increase Of Capacity Through Optimised
Timetabling

Abstract
The throughput of track infrastructure and the quality of railway services can be
enhanced by a set of intelligent scheduling measures provided that the timetable
design takes the variations of real operations sufficiently into account. Small
variations of the train running and dwell times are currently compensated for by
standard time supplements and margins between train paths, which, so far, are
mainly based on rules of thumb, sometimes checked by simulation. The paper
discusses the current methods to estimate characteristic timetable variables as
minimal time headway, slack and waiting time. A new stochastic approach is
presented for the estimation of blocking times and buffer times at bottlenecks
based on the distributions of the start and of blocking time ‘waves’ of trains,
which aims at reflecting the interaction between trains following each other on
saturated routes
