This paper reports on the development of a formal model for the Hybrid ERTMS/ETCS Level 3 concept in Electrum, a lightweight formal specification language that extends Alloy with mutable relations and temporal logic operators. We show how Electrum and its Analyzer can be used to perform scenario...

Various projects in Australia are discussing the introduction of the European Train Control System Level 2 (ETCS L2) and the European Rail Traffic Management System (ERTMS). Australian rail operators are hoping that this will open up new opportunities in terms of digitalization and efficiency of ...
This paper presents a formal model of the case study proposed for the ABZ2018 conference, which concerns the Hybrid ERTMS/ETCS Level 3 Standard. This standard allows trains to communicate with a train supervisor to report their integrity and positions, thanks to an onboard...
This includes the correction of errors (Article 10) in the current specification (about 41 CRs for ETCS and about 8 CRs for GSM-R) and the Game Changers (ATO, GNSS, Level 3, FRMCS, 鈥 ) which are expected to be introduced in the next TSI, initially planned in 2022 but probably ...

Several Shift2Rail projects aim to investigate the application of formal methods to new ERTMS/ETCS railway signalling systems that promise to move European railway forward by guaranteeing high capacity, low cost and improved reliability. We explore the ERTMS/ETCS level 3 full moving block ...
