Contact Marco Gerlach at the Brunswick office
Marco Gerlach is a member of the Executive Board and Head of Railway Engineering at NEXTRAIL GmbH. With over 20 years of professional experience on the manufacturer side, he has extensive operational and technical expertise as a consultant in the railway sector - particularly in the areas of digital interlocking (DSTW), electronic interlocking (ESTW) and train control and signalling systems (ZZS).
He is familiar with the basic principles of construction and approval (railway, construction and operating regulations, sector guidelines, administrative regulations of the Federal Railway Authority and tram construction and operating regulations) and has methodological expertise in risk assessment and evaluation by CSM-RA. Thanks to his many years of experience as a sales and project manager, he also has extensive knowledge of project management, understanding and evaluating complex system contexts and the technical management and cooperation of interdisciplinary teams.
Marco Gerlach graduated with a degree in industrial engineering from TU Braunschweig.

ETCS Digital S-Bahn, S-Bahn Hamburg. World’s first implementation of ATO over ETCS with GoA 2.
The challenging new line with 12 tunnels and 37 bridges was equipped for regular operation at 250 km/h with ETCS Level 2 without conventional signalling (ETCS L2oS).
As part of equipping of the new line with ETCS Level 2 without conventional signalling, NEXTRAIL has taken over the tasks of the CSM assessment to adopt the requirements of BTSF 2.3 for operation without signals and has drawn up the safety plan for process conformity in accordance with DIN EN 50126.
The new interlockings at the Wilchingen-Hallau and Neunkirch stations are located on the main railway line Mannheim–Basle–Constance. Both stations were equipped with mechanical interlocking systems of the Bruchsal design (built in 1928), which were replaced by an electronic interlocking system.
The scope of measures covered renovating the signalling of the outdoor and indoor facilities as well as signalling modifications to the electronic interlockings with adjustment ranges in Erzingen and Beringen, respectively. In addition, a permanent track change operation with a Zs6 signal was established between the operating sites. The scope of services included the implementation of the CSM-RA (system definition, system limits, coordination with the assessment body).
An ETCS Level 1 limited supervision/signal-controlled ETCS Level 1 train control system was introduced on the Swiss cross-border lines (German railway lines on Swiss territory and the adjacent DB Netz AG lines in Germany).
For the reliability testing of the signal-controlled ETCS Level 1 trackside train control system, NEXTRAIL has drawn up a reliability testing plan for the generic signal-controlled ECTS route installation sub-system.
On the 21 S-Bahn line in Hamburg, trains will operate automatically for the first time on an S-Bahn network with ATO over ETCS in regular operation. NEXTRAIL was tasked with providing expert know-how to support the project in terms of the generic aspects of ETCS and ATO in the areas of system development and approval management, as well as in test and commissioning management.
As part of this project, the ATO over ETCS system with GoA2 was approved for the first time, assessed in terms of safety and successfully put into operation.
In addition, NEXTRAIL prepared the risk analyses according to CSM-RA, the evaluation of the ATO specification, the impact analysis, the system definition for the fully automatic shunting operations and the system definition for the AVVO test drives.
At the same time, it marks the world’s first implementation of the German regulation on granting operating authorisation for the railway system (EIGV) and the testing of the German sectoral guideline for the authorisation assessment of signal, telecommunication and electrotechnical facilities.
