Friday Brief: Siemens buys Mermec rail diagnostics and signalling units

Siemens buys Mermec rail diagnostics and signalling units
INDUSTRY: Siemens Mobility has agreed to acquire the core rail diagnostics, signalling and data infrastructure businesses of Italian group Mermec, adding roughly EUR 430m in annual revenue and around 1,700 staff to its rail technology operations.
The acquisition consolidates two adjacent layers of the digital rail stack — diagnostics and signalling infrastructure — under a single operator with global scale. Mermec’s customer base spans more than 70 countries.
Three Mermec units remain outside the deal and will continue as independent signalling businesses under Angelo Holding. Regulatory clearance is required; close is expected before end of 2026.
The transaction follows Vossloh’s move to acquire LiDAR specialist Cordel Group, announced a day earlier — two acquisitions targeting the same segment of automated rail infrastructure monitoring within 48 hours.
Three operators, one gatekeeper: Germany’s high-speed market opens
Three operators have independently concluded that Deutsche Bahn’s hold on Germany’s high-speed network is weak enough to enter — but one infrastructure manager holds the key to whether any of them can.

Italo has set end of May as the deadline for DB InfraGO to confirm train paths. Without confirmation, a EUR 1.2bn contract with Siemens Mobility for 26 high-speed trainsets cannot be signed and the 2028 launch becomes unviable.
DB InfraGO has not responded publicly. The June contract deadline will answer instead.
Vossloh moves to acquire UK rail data firm Cordel
INDUSTRY: Vossloh has agreed to buy British LiDAR specialist Cordel Group for £29m (approximately EUR 33m) — a 107% premium over the company’s pre-announcement share price — adding automated 3D track inspection and AI-based data analysis to its infrastructure monitoring portfolio.
Cordel’s board recommended the offer unanimously on 13 May. The deal is subject to shareholder approval and UK regulatory clearance under the National Security and Investment Act, with closing targeted for Q3 2026.
France signs Bordeaux–Toulouse high-speed funding deal
FRANCE: State and regional funding for the Bordeaux–Toulouse high-speed line is now committed, moving a project three decades in the making from political intent to binding obligation.
Prime Minister Lecornu signed the protocol in Toulouse on 7 May. The state contributes EUR 410m across 2026 and 2027, matched by an equal contribution from regional and local authorities, with the EU covering the remaining 20% under the TEN-T framework.
First procurement tenders are to be launched before end of 2026. The line targets opening in 2032–33, cutting the Bordeaux–Toulouse journey to approximately one hour.
EU proposes single ticket for cross-border rail
EU: The European Commission has proposed a single ticketing system for cross-border rail travel. The proposal would require national operators to sell competitors’ tickets on their own platforms and would give passengers full protection of their rights across operators in a single booking.
Operators with a national market share of 50% or above would be required to open their ticketing platforms to any requesting operator or service organiser. The three proposals, adopted 13 May, now enter the ordinary legislative procedure — Council and Parliament must both approve, and no adoption timeline has been set.
