The new system is intended to replace the monitoring system supplied with the fleet when it was built, replicating its existing function while adding monitoring to address fleet operating needs and component obsolescence. It will monitor train systems while units are away from their primary depot and review system history so maintenance can be targeted before a train has to be stopped for examination. This is a rail fleet monitoring and associated software service, rather than a general-purpose monitoring system. The stated delivery country is the United Kingdom. The process is at planning: TSGN has set out its intention to procure, but has not issued an invitation to tender. It plans preliminary market engagement, with a scheduled engagement milestone on 2 November 2026. The indicative contract period is 1 November 2027 to 31 October 2030. The published estimated gross value is £0. No procurement procedure, award method, evaluation criteria, eligibility conditions or lot-specific scope is set out in the available planning details. The market engagement is the stated next step for suppliers to learn about and inform the prospective requirement; the date given is the buyer’s planned engagement milestone, not a tender submission deadline. The requirement is most relevant to suppliers able to provide remote condition monitoring for rail rolling stock, including the monitoring system and associated software or information systems. The buyer is looking for a solution for Class 171 units that can reproduce the current system’s function and extend monitoring to reflect fleet operations and component obsolescence. Suppliers with relevant experience in train systems monitoring, rolling-stock maintenance support and analysing system histories to help plan maintenance would be well placed to engage with the emerging requirement. The intended use is operational: monitoring while units are away from their primary depot and identifying maintenance needs before units must be stopped for examination. The planning-stage market engagement offers relevant suppliers a chance to discuss this developing requirement before a tender is issued. ## Notice GTR is looking to introduce a new RCM system to its Class 171 fleet, replacing the current system from the original build. The intention of the new system is to replicate the current system with additional monitoring requirements based on fleet operation and component obsolescence. The system will monitor the performance of systems while away from the primary depot and review the history to target maintenance activities in advance of a unit being stopped for exam.
