Signalling, Communications & Train Control

Train data recorders capture and store key operational information such as speed, braking, acceleration, fuel or energy consumption, and driver actions. These systems support incident investigations, maintenance planning, and performance monitoring, and are an important part of safety and compliance in modern rail operations. Suppliers in this category provide data recorder solutions for all types of rolling stock.

Diagnostics and fault logging systems monitor the performance of trains in real time, detecting and recording irregularities, malfunctions, or failures in on-board systems. These tools support predictive maintenance, reduce downtime, and improve operational safety by providing early warnings of potential issues. Suppliers in this category offer diagnostic solutions and fault loggers designed specifically for use on rolling stock.

Driver-Machine Interfaces (DMIs) and On-Board Units (OBUs) are essential components of modern train control and signalling systems. DMIs provide real-time information to the driver and allow interaction with onboard systems, while OBUs handle data processing, communication, and signalling functions. Suppliers in this category provide complete DMI and OBU solutions, as well as components and technologies that support their integration and functionality.

Radio, GSM-R and FRMCS equipment enables communication between train drivers, dispatchers and other railway personnel. This includes analogue radio systems, GSM-R systems standardised for railway use, and emerging FRMCS technology based on 5G. Suppliers in this section provide transceivers, antennas, power supplies and other communication components for rolling stock.

On-board signalling and train control software supports safe and efficient train operations. Suppliers in this section provide software solutions for functions such as automatic train protection, train control, and communication-based train control systems.

Train control and scheduling systems are used to plan, coordinate and manage train movements across the network. These solutions help operators optimise timetables, allocate paths, manage capacity and respond to delays or disruptions in real time. Suppliers in this category provide software that improves punctuality, network efficiency and operational resilience.

Train management equipment facilitates communication between train and trackside systems to help manage traffic, improve efficiency and ensure safety. This section features suppliers of systems that support functions such as train location, routing and control.
