Abstract
Train rescheduling plays a vital role in railway operation. Many factors should
be considered in the train rescheduling process and train class, delayed time,
remaining distance and current position are the most common ones. There are
usually different measures aiming at corresponding factors and combinations of
the measures with different priorities compose various train rescheduling
strategies. Furthermore, different strategies lead diverse results and they are
applicable to various scenarios respectively. This paper researched the effects of
different train rescheduling strategies in the background of Wuguang passenger
dedicated line by means of simulation experiments. It analyzed class-based
strategies first and achieved the suitable strategy and its related parameters. Then
it analyzed the influence of different combinations of high-speed strategies and
middle-speed strategies under different perturbation scenarios.
Keywords: train rescheduling strategy; passenger dedicated line; simulation.
1 Introduction
Train rescheduling is the key work in railway operation. Its basic idea is to
determine a new order of the trains when some perturbations make current
schedule disordered and infeasible. Many factors should be considered together
and corresponding measures will be taken in this process. The measures and their
various combinations compose different train rescheduling strategies which will
probably lead diverse results and are applicable to various scenarios respectively.
Because of high density and high speed of trains, train rescheduling work in
Chinese Passenger Dedicated Lines (PDL) is more difficult than that in
