"We are increasingly moving to a system of risk-based maintenance that allows us to monitor our assets, judge how well they are performing and then decide when to carry out maintenance work or renewals based on real-time, accurate data and judgements about criticality."
Network Rail also aims to better align the information it provides to customers about their journeys across all channels.
"We plan to improve the consistency of information across stations. We're integrating the different systems we use into one which will feed into screens at stations, apps on smartphones and websites, and on-train information," it said.
It added: "Our aim by 2019 is to operate the best possible timetable every day on the network, and to be nearer our goal of operating a 'right time' timetable which uses GPS equipment on trains to ensure the right train is at the right place at the right time."
In January, the railway operator signed a £65 million, five-year deal with Computacenter to transition and transform its desktop services.
Meanwhile, last year, Network Rail signed framework agreements with Accenture, BAE Systems Detica, Cognizant, CSC and TCS to simplify its IT and computing relationships.
The company currently works with more than 270 individual IT suppliers and manages a variety of systems of varying complexity, including some that were designed as far back as the 1970s.
