Rail Performance


Our passengers deserve a high quality, reliable and punctual service, so we’ve introduced a new set of performance metrics, unique to TfW, focussed on delivering a greater experience for our passengers. 

In the past, rail targets were measured by Public Performance Measures which meant that it would be acceptable for a train to be late for most of a journey but arrive on time at last scheduled stop. Often this would be achieved by missing stops to ‘catch up’ with the timetable.

TfW doesn’t believe that this approach is  right for our passengers, so we’re measuring two essential targets, to help improve our services and customers’ journeys: Passenger Time Lost and Short Formations. 

Passenger Time Lost is a new metric which measures average lateness at multiple stops on a journey, allowing  us to track our customers’ experiences with the aim to ensure that passengers arrive at their destination on time. 
Short Formations takes in account of capacity, where it measures the percentage of services that operate below the capacity required in the timetable 

We’re aiming to provide our customers with the best possible service and believe that these new targets ensure that passengers are not consistently impacted by cancellations and missed station stops during times of disruption.
