Europe Communication-Based Train Control Market Size

Europe communication-based train control market was valued at USD 750.3 million in 2025. The market is expected to grow from USD 805.7 million in 2026 to USD 1.58 billion in 2035 at a CAGR of 7.8%, according to latest report published by Global Market Insights Inc.

In December 2025, Siemens Mobility and Sporveien commissioned an advanced CBTC system on the Oslo Metro, the first deployment of its kind in Norway as part of a €270 million modernization of the aging signalling infrastructure. The new system immediately boosted capacity from 28 to 36 trains per hour on an initial section of the network, addressing crowding and improving service reliability and efficiency.
 

The Digital Automatic Train Control (CBTC) system will allow for a large reduction in train headway, increasing throughput which is very important for the density of metro networks in cities such as London, Paris, Berlin, Amsterdam. All these networks will be required to accommodate the growth in urban public transit demand over the next few decades.
 

EU commitments with regards to the European Green Deal and Sustainability Goals are helping to drive the investment in efficient, low-emission public transit systems; the CBTC systems will be a major part of those investments.
 

The integration of automated train operations (GoA4), Artificial Intelligence (AI) and Predictive Analytics is enhancing the appeal of CBTC for urban and longer distance rail operations by increasing reliability and operational safety.
 

Europe Communication-Based Train Control Market Trends

The rising trend of developing European metro system operators to use CBTC for semi-automated and full driverless train operations is supported by an increasing need to improve operational costs, maximize the number of trains operated in service (operating frequency), and enhance the safety of public transit. City authorities are upgrading their highly congested metro corridors to either GoA3 or GoA4 to meet the need to meet the growing demands of Urban Commuters.
 

In January 2025, Alstom signed a contract with Metro de Madrid to upgrade signaling on Line 6 using Urbalis CBTC technology and advance it to Grade of Automation 4 (fully driverless operations). This marks a significant step toward higher automation levels, improving frequency, reliability, and energy efficiency on one of Madrid’s busiest metro lines.
 

A major trend being observed in Europe is the integration of CBTC and ETCS with a Centralized Traffic Management System (CTM). The goal of developing such hybrid signaling architecture is to facilitate interoperable operation of the metro systems, the suburban rail systems, and the mainline railway systems. In addition, the hybrid signaling systems will permit a smoother flow of trains from urban areas to cross border locations in the EU as per the EU harmonization goals for railways.
 

CBTC's reliance on wireless communication plus data available in real-time means that cybersecurity has become an urgent priority for both design and procurement. Considering this, European operators have identified the critical need for CBTC systems to have secure communications systems, redundancy in the event of network failures, and built-in resilience to cyber threats in order to maintain safe and uninterrupted train services in compliance with the EU’s rigorous safety requirements.
 

CBTC systems across Europe are rapidly evolving into data-driven platforms that enable predictive maintenance and performance optimization. With operational data being captured and analyzed using real-time technology, operators can improve equipment reliability, reduce energy consumption and prolong the life of train systems. These trends are both cost-effective and aligned with the EU’s environmental sustainability goals as well as the EU’s digital transportation strategy.
 

Europe Communication-Based Train Control Market Analysis
