Forecasting Robustness Of Timetables
Author(s)
W. Barter
Abstract
Ultimately, the timetable is proof of the capacity of a rail network. If a train can
be pathed, then capacity exists. However, a crucial variable is the extent of spare
capacity or \“slack”, intended to allow recovery from the minor disruption that is
inevitable in real life. Fundamentally, the ability to absorb some disruption trades
off against full exploitation of nominal capacity.
The number of trains that can be built into a timetable also depends on many
factors apart from the technical characteristics of the infrastructure and trains,
such as the mix of trains and their stopping patterns. Usable capacity therefore
varies depending upon how it is used to reflect commercial and political
requirements. In the UK, these requirements are increasingly embodied in the
Strategic Rail Authority’s Route Utilisation Strategies, which aims to prioritise
allocation of route capacity whilst preserving robustness. Whils
