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 activities taking place to improve our network. Here are a few things we are doing this year:

  • Continuing to rollout the Arterio trains to replace the suburban fleet.
  • £129m investment in the re-signalling from Farncombe to Petersfield, including the renewal of nine level crossings.
  • Queenstown Road Track Renewal to remove multiple reoccurring faults in the area.

PERFORMANCE TARGET FAILURE EXPLANATION

Reporting Period: P05

Performance Target: Punctuality

Target: 84.4%

Actual Performance: 81.9%

Variance: -2.5%

Summary

SWR did not achieve the Punctuality Performance Target during Period 5, achieving 81.9% against a target of 84.4%.

Therefore, the Operator failed to achieve the above Performance Target during the reporting period.

Cause(s) of the relevant Performance Target Failure:

Most of the target miss was driven by fixed infrastructure, which accounted for over half of the overall variance. This was mainly driven by track faults (emergency speed restrictions at Berrylands, Brockenhurst and Ashurst, alongside condition of track incidents at Earlsfield and Raynes Park), and third rail faults (due to the restricted power supply between Brockenhurst and Christchurch because of the recent substation fire).

Weather and fleet also made contributions to the adverse position, with most of the weather variance caused by lineside fires, and continuing reliability challenges across the SWR fleet.

Actions to Remedy Failure:

  • We are investing in improved technologies to provide remote visibility of fixed infrastructure (such as on train detection technology), particularly in hot weather, which will help maintenance teams prioritise tasks and upskilling colleagues to help reduce the time it takes to rectify faults.
  • We continue to see improvements in Arterio fleet performance and expect performance and reliability to improve, in line with the performance improvements seen on other new rolling stock fleets over the course of their introduction to service.
