Timetable Advisory System (TAS)


Developed by SNC-Lavalin, with support from Network Rail, freight and passenger operating companies, the Timetable Advisory System (TAS) is helping commuter rail passengers and freight in the UK get to destinations on time, while improving energy consumption and capturing valuable delay information.

Energy efficiency = Savings

Designed to operate on a tablet in a driver’s cab, TAS provides a range of information about how trains are operating relative to the timetable. If a train is running ahead of schedule, the driver can reduce speed to save energy for operators (modeled scenarios indicate running a train to timetable can reduce energy use by eight percent). If a train is behind schedule, the driver can accelerate to minimize delays, helping passengers and freight get to their destination more rapidly, reducing delays on route, and generally helping the UK rail industry to run an on-time railway.
