Knorr-Bremse and Trenitalia are jointly implementing Knorr-Bremse’s digital electromechanical braking system with brake-by-wire technology on a regional train in Italy that has entered regular service. The project marks the first deployment of the EM Brake in daily rail operations and will provide operating data for further development of the technology. The EM Brake replaces the pneumatic and hydraulic components used in conventional braking systems with electrical transmission of the braking signal and electromechanical generation of braking force through electric motors.
Matthäus Englbrecht, CTO of the Knorr-Bremse Rail Division, said Trenitalia has worked with new rail technologies at an early stage and integrated them into operations. He said the EM brake has the potential to improve performance, energy efficiency and maintenance, while the first deployment in regular service will provide further information needed to support its use across different vehicle types and standards.
The electromechanical brake calipers offer faster response times, precise brake-force control and shorter stopping distances. These characteristics can improve safety, stability and reliability in rail operations. The system also has fewer components than conventional braking systems, allowing it to be lighter and reducing the energy required to operate trains. Its design can also simplify installation, servicing and retrofitting while helping operators manage lifecycle costs.
The EM Brake includes telemetric monitoring and diagnostic functions from delivery, including predictive maintenance capabilities. Knorr-Bremse said these functions can help operators identify potential maintenance requirements and improve the management of braking systems. The technology is also part of the company’s development of an “airless train” concept, in which compressed-air and hydraulic systems traditionally used in rail braking could eventually be replaced by electrical systems.
Simone Mantero, Managing Director of Knorr-Bremse Rail Italy, said the rail industry needs new technologies to improve efficiency and competitiveness. He said the project with Trenitalia demonstrates the importance of cooperation between rail operators and technology suppliers in moving new systems from development to operational use.
Knorr-Bremse will also demonstrate the EM braking system at its booth during InnoTrans, scheduled for September 22-25, 2026. The demonstration will show the system’s braking and monitoring capabilities. The company said the Trenitalia project will generate further operating experience for the EM Brake and support its development for wider applications across rail vehicles. The technology is being positioned as an alternative to conventional pneumatic and hydraulic braking systems, with potential applications in new trains as well as retrofit programmes. The project also reflects the wider shift towards digital and electrically controlled rail systems, with braking technology increasingly linked to onboard monitoring, diagnostics and predictive maintenance.
