TRUST

This article is about a train monitoring system. For other uses, see Trust (disambiguation).

TRUST (Train Running Under System TOPS) is a Network Rail computer system used for monitoring the progress of trains and tracking delays on Great Britain's rail network.^[1] It compares actual train movement events with those planned, allowing delays to be recorded with explanations as to the cause allowing the operation of an incentive scheme to reduce delays.^[2]

TRUST is used to record when a train passes a measuring point, which can be used to identify delays, and the cause of the delays.^[3] It is based on the TOPS mainframe-based computer system. ^[4]

TRUST data is part of Network Rail's open data feed, which is publicly-available to encourage innovation in customer information both inside and outside the railway industry. Such data is used by various websites and companies as a source for train movements and cancellations in a variety of applications. A similar computer system is Darwin, from the Rail Delivery Group.^[5]
