TOPS is a mainframe system procured by British Rail (BR) from Southern Pacific in the early 1970s. It is a complex, command-driven system, originally designed for the management and control of freight vehicles and trains to provide real-time information of the whereabouts, loading, consignee, condition, etc. of freight vehicles. Since the introduction of TOPS to BR, the system has been expanded to handle locomotive activities and information about loco-hauled passenger operations, via a sub-system named POIS. The average freight traffic is currently 500 trains per day but may increase going forward. ## CPV classification Industry specific software development services Software package and information systems Industry specific software package Information technology services Source Find a Tender (UK) · Notice ocds-h6vhtk-059fe0-2025-09-23T10:37:21+01:00 [View official notice](https://www.find-tender.service.gov.uk/Notice/ocds-h6vhtk-059fe0-2025-09-23T10:37:21+01:00) Never miss a tender like this again Get AI summaries, deadline alerts and a bid pipeline for tenders matched to your business.
