An alternative graph formulation for train service planning under ETCS Level 2, Moving Block and Virtual Coupling signalling systems with dynamic speed supervision and continuous infrastructure representation

To help maximize utilization of its existing infrastructure, the railway industry requires train service optimization models with headway constraints for state-of-the-art distance-to-go signalling systems. To this end, this paper introduces an approach for assessing train path feasibility in ETCS Level 2, Moving Block, and Virtual Coupling, that...

Assessing Moving Block Railway Capacity Based on Fixed Block Infrastructure Occupation

Moving block signalling promises a significant reduction of the infrastructure occupation compared to a fixed block system, such as NS’54/ATB. This is mainly caused by a strong reduction of the approach and running time. However, to assess the capacity gains track occupation data, such as blocking times are needed. ETCS L3 Moving Block is still...

Multi machine approaches for conflict resolution under moving block signalling

Railway networks are to play an increasingly large role in European transportation. This has boosted the urgency of railway innovations, of which the development of decision support systems for conflict resolution is an important aspect. This research contributes to this development by formulating a suitable mathematical approach for railway...

A hybrid Delphi-AHP multi-criteria analysis of Moving Block and Virtual Coupling railway signalling

The railway industry needs to investigate overall impacts of next generation signalling systems such as Moving Block (MB) and Virtual Coupling (VC) to identify development strategies to face the forecasted railway demand growth. To this aim an innovative multi-criteria analysis (MCA) framework is introduced to analyse and compare VC and MB in...

Raising frequencies on a high-frequency metro network and how new technologies can improve timetable reliability: a case study in Rotterdam

Mass rapid transit plays an important role in providing a sustainable form of transport in densely populated areas. Public transport operators worldwide are experiencing an increase in popularity of their network and are experiencing ridership growth on their metro networks. To accommodate ridership growth, many transport operators are tasked...
