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...

ERTMS/ETCS Hybrid Level 3 and ATO: A simulation based capacity impact study for the Dutch railway network

In the 2020 timetable the Dutch legacy signalling and automatic train protection systems (ATB/NS’54) are operating at maximum capacity in the busiest parts of the network. With future expansions of services in mind, the capacity provided by the legacy systems could be considered insufficient. The planned implementation of the ERTMS/ETCS Level 2...
