Personal project references for Christian Klier
As part of the Digital node Stuttgart project, automatic train operation (ATO) over ETCS is used to implement automated driving operations with train drivers at automation level 2 (GoA 2). The aim is to increase punctuality in the timetable, increase capacity and drive in as energy-optimised manner as possible during scheduled operation. In this context, NEXTRAIL supports the processing of content throughout all project phases and is primarily responsible for the operational and functional aspects of ATO. In addition, NEXTRAIL supports the project teams of DB Netz AG in system and project development for the peripheral systems Capacity & Traffic Management System (CTMS) and Digital Register.
Carrying out the simulation and preparation of the railway management study on the potential for increasing quality and capacity on ETCS/ATO routes as well as increasing the stability of driving operations by means of an improved on-board braking system.
Product owner, project manager and team leader at Siemens in the development of the Advanced Vital Vehicle Operation (AVVO) system component as a vital addition to the ATO/ETCS system for carrying out the unattended automatic operation (GoA 4) of an S-Bahn vehicle. The development included the integration of ETCS onboard, vehicle control, ATO onboard, ATO route, 5G communication to the landward side and the development of software safety integrity level (SIL) 2 in accordance with CENELEC EN50128, EN50129, EN50159.
