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 the last scheduled stop. Often this would be achieved by skipping stops to ‘catch up’ with the timetable.
TfW doesn’t believe that this approach is right for our passengers, so we’re measuring three essential metrics, to help improve our services and customers’ journeys: Passenger Time Lost, Cancellations and Short Formations. These focus on punctuality, reliability and capacity respectively.
Passenger Time Lost is a new metric which measures punctuality (to within 3 minutes) at every recorded station stop on a journey whilst taking account of the number of passengers arriving at their destination. This allows us to track our customers’ experiences with the aim to ensure that passengers arrive at their destination on time.
Cancellations measures the reliability of the service, and Short Formations takes into account the capacity of the service, by measuring the percentage of services formed with fewer passenger vehicles than planned in the train plan.

Service provision
| KPI Name | KPI Description | Period Actual | Prior Period Actual | Prior Year | Period MAA |
| Passenger Time Lost (PTL) - Core Valley Lines | The percentage of services arriving within 3 minutes of the scheduled arrival time, whilst applying a weighting to locations which service our highest volume of customers across the Core Valley Lines. Delays at higher footfall locations have a greater impact on the PTL percentage. | 91.7% | 88.3% | 90.9% | 85.7% |
| Passenger Time Lost (PTL) - Wales and Borders | The percentage of services arriving within 3 minutes of the scheduled arrival time, whilst applying a weighting to locations which service our highest volume of customers across the Wales Borders Lines. Delays at higher footfall locations have a greater impact on the PTL percentage. | 79.6% | 81.5% | 78.0% | 75.1% |
| On-the-Day Cancellations | The percentage of service cancellations (service reliability) across the network. To align with industry standards and Network Rail, Cancellations have been recalculated taking 0.5 for part and 1.0 for full. | 4.4% | 3.9% | 3.4% | 5.4% |
| Short Formations | The number of services that operate below the capacity required in the timetable. | 9.4% | 9.8% | 9.9% | 12.2% |
