Behind the Scenes of a Pleasant Train Journey: Testing Strategies to keep 3.3m Trains on Track, on Time

T7     Start Time : 16:15     End Time : 17:00

Talk Abstract:

As a train passenger you want to enjoy your journey from one station to the other. Have nice views on the landscape you are passing and arrive in time on your destination.

But behind the scenes it takes a lot of effort to enable passengers to enjoy their journey. Complex computer systems are needed to ensure trains are running in time and in a safe way.

ProRail is a Dutch company responsible for maintaining the railway infrastructure (tracks, switches, signals, GSM-R network and stations) and for controlling the rail traffic. The Netherlands has one of the busiest and dense rail traffic in the world. Around 3.3 Million trains per year are running on a tight time schedule to transport around 1.2 Million passengers each day. Therefore, the train traffic control systems must always be up-and-running, but above all ProRail must provide safety on the tracks.
