Signalling Control System - Preliminary Market Engagement Notice

To continue to enhance the safety environment for railway track workers, passengers and the public Network Rail need to introduce technology which enhances safety controls and enables work to be undertaken more efficiently.

Through this Preliminary Market Engagement Notice, Network Rail would like to understand available, or significantly developed, solutions for track worker controlled secondary/additional protection that does not require trackside devices on the current network. This is assumed to require either an update or addition to an existing signalling control system or a control centre device that interfaces to the signalling control system. In either case, a connection would then be made to the track worker to allow them to apply and remove the additional protection using a remote device.

The purpose of this Preliminary Market Engagement Notice is to allow Network Rail to understand:

• What solutions to the problem statement are currently available? And/or potentially available soon.
• What can the market offer?
• Which systems would it work with?
• What, if anything, would Network Rail need to change or adapt for successful implementation?
