Our performance

Our latest punctuality and reliability figures

At South Western Railway we know that you want a safe, reliable, punctual service. We’re committed to providing this, to help deliver the best service we can.

We continually measure our service reliability and punctuality and report on how we are performing against targets which are set in our Passenger’s Charter.

All our services are monitored every day, including Sundays and Bank Holidays and we have a range of performance metrics in place to measure the levels of performance we are delivering to our customers including;

Public Performance Measure (PPM) – the percentage of Passenger Services that arrive at their final scheduled destination within five minutes of the advertised time, without being subject to any form of cancellation.

Cancellations and Significant Lateness (CaSL) - the percentage of Passenger Services which are cancelled, or arrive significantly late at their final scheduled destination. Significantly late defined as 30 or more minutes late.

All Cancellations – the number of Passenger Services which are cancelled for all or part of their planned schedule including those services that Fail to Call at any intermediate stations on route as planned.

All Cancellations excluding Failures to Call – the number of Passenger Services which are cancelled for all or part of their planned schedule excluding any cancellations caused by services Failing to Call at any intermediate stations on route as planned.

Right Time – the number of Passenger Services that arrive early or within 1 minute of their final scheduled destination, without being subject to any form of cancellation.

Lateness – the percentage of Passenger Services which are late in arriving at their final scheduled destination, without being subject to any form of cancellation by; a) between 1 and 14 minutes (within 15 minutes), b) between 15 minutes and 29 minutes c) between 30 minutes and 59 minutes; d) between 60 minutes and 119 minutes; and e) 120 minutes or more.

Short Formations – the number of Passenger Services formed with fewer vehicles than specified in the Capacity Statement approved by the Department for Transport. Services cancelled in full or in part are excluded from this metric as they are already accounted for under various cancellation metrics.
