Providing innovative solutions to locomotive domain in both ERTMS and Metro trains.

Locomotive signaling systems, also known as train control systems, play a crucial role in ensuring the safe and efficient operation of trains on railways. These systems face several technical challenges due to the complexity of the railway environment and the need for reliable communication and control. Here are some key technical challenges in locomotive signaling systems:

1. Safety and Reliability: The foremost challenge in train control systems is ensuring safety and reliability. Signal systems must be designed to prevent collisions, maintain safe distances between trains, and respond to emergency situations promptly. Achieving high reliability and fault tolerance in signaling components and communication networks is crucial.

2.Communication and Data Integrity: Train control systems rely on effective communication between trains, wayside equipment, and central control systems. Ensuring reliable data transmission, even in harsh environmental conditions, is a challenge. Maintaining data integrity, error detection, and correction mechanisms are vital to prevent signal errors and maintain accurate train positioning information.

Our core team has strong expertise in Locomotive sub systems like Automatic Train Protection, Wayside systems RBC, Speed Sensor unit and Fire Detection Unit.


The European Rail Traffic Management System (ERTMS) is a single European signaling and speed control system that ensures interoperability of the national railway systems, reducing the purchasing and maintenance costs of the signaling systems as well as increasing the speed of trains, the capacity of infrastructure and the level of safety in rail transport.

The European Railway Traffic Management System (ERTMS) is a major industrial project developed by eight UNIFE members – Alstom Transport, AZD Praha, Bombardier Transportation, CAF, Hitachi Rail STS, Mermec, Siemens Mobility and Thales – in close cooperation with the European Union, railway stakeholders and the GSM-R industry.

ERTMS has two basic components

ETCS, the European Train Control System, is an automatic train protection system (ATP) to replace the existing national ATP-systems;

GSM-R, a radio system for providing voice and data communication between the track and the train, based on standard GSM using frequencies specifically reserved for rail application with certain specific and advanced functions. For more information on GSM-R, please click here.

ERTMS aims at replacing the different national train control and command systems in Europe. The deployment of ERTMS will enable the creation of a seamless European railway system and increase European railway’s competitiveness.

Metro Trains:

Metro is a type of high-capacity public transport generally found in Urban areas. Unlike buses or trams, rapid transit systems are electric railways that operate on an exclusive right of way, which cannot be accessed by pedestrians or other vehicles of any sort, and which is often grade separated in time tunnels or on elevated railways.
