In-Cab Signaling and Train Control

In-Cab Signalling and Train Control

Modern technologies have allowed train control to move from trackside signals to in-cab displays authorizing the driver to proceed. Where required, the remaining functions of the driver can be mechanized, allowing the train to operate fully automatically. Our Rail Control Systems team has unparalleled experience of the Computer-Based Train Control Technologies (CBTC) driving this change on metro systems and the European Train Control System (ETCS) and Positive Train Control (PTC) being deployed on mainline infrastructure around the world.

Fitting these technologies is only part of the change required to deploy in-cab signaling; significant transformations in operations and maintenance practices are also needed. To gain the full capacity, reliability and financial benefits of the upgrade, infrastructure changes ranging from power supply and track upgrades to in-cab CCTV and Traffic Management Systems must be considered. If in-cab signaling is used to provide unattended and driverless operation, even more radical infrastructure changes may require, such as platforms screen doors and obstacle detection systems.

We take a holistic approach to implementing in-cab signaling technologies. Alongside our train control expertise, we have deep capabilities in all associated infrastructure areas, as well as railway operations, human factors, rolling stock fitment, high-integrity communications, migration from legacy signaling, reliability and safety assessment and electromagnetic compatibility so we can optimize the upgrade from a whole-railway perspective. We also have experience in leading and supporting the stakeholder engagement and change management activities required to ensure that operators, maintainers, analysts and other business stakeholders adapt their processes and mindsets to work optimally with the new technology.
