Assessing The Resilience of Railway Organisation For Unexpected External Events: Development of a Semi-Qualitative Assessment Tool

The railway transportation system is a critical infrastructure that supports the functionality of a country through ways like the transportation of people from point to point to carry out their daily activities i.e., work, study, and leisure; the timely transportation of freight within a country or cross-borders, contributing to economic...

Resilience assessment of railway networks: Combining infrastructure restoration and transport management

During railways operations, unplanned events might occur which can result in rail traffic being heavily impacted. The paper proposes a passenger-centred resilience assessment for disruption scenarios which consist of multiple simultaneous disruptions. It combines train traffic operations, passenger flows and network restoration. To evaluate...

A Matheuristic for the Integrated Disruption Management of Traffic, Passengers and Stations in Urban Railway Lines

In big cities, the metro lines usually face great pressure caused by huge passengers demand, especially during peak hours. When disruptions occur, passengers accumulate quickly at stations. It is of great importance for dispatchers to take passenger flow control into consideration for the traffic management to ensure passengers' safety and to...

Estimating impacts of covid19 on transport capacity in railway networks

Due to the covid19 crisis, public transport (PT) systems are facing new challenges. Regarding restrictive measures such as physical distancing and the successive returning of passengers after the “intelligent lockdown”, significant lack of transport capacity can be expected. In this paper, the transport capacity of a PT network is assessed,...

Adjusting freight train paths to infrastructure possessions

This paper tackles railway timetabling with infrastructure work possessions. It introduces the integrated Passenger and Freight Train Timetable Adjustment Problem (PF-TTAP) which handles both passenger as well as freight trains. To deal with possessions, passenger trains are typically retimed, reordered or partially cancelled, while for freight...
