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: P06
Performance Target: Punctuality
Target: 86.4% (mid-point of range)
Actual Performance: 83.9%
Variance: -2.5%
Summary
SWR did not achieve the Punctuality Performance Target during Period 6, achieving 83.9% against a target of 86.4%
Therefore, the Operator failed to achieve the above Performance Target during the reporting period.
Cause(s) of the relevant Performance Target Failure:
"The majority of the target shortfall was driven by infrastructure-related issues, which accounted for 96% of the overall variance. While some of the impact was driven by track faults, speed restrictions accounted for most of the variance. In particular, a higher number of temporary speed restrictions were required across parts of the network while track conditions were assessed and safety checks completed. While these restrictions can impact punctuality, they are an important precaution to ensure the safe operation of the railway.
A small proportion of the variance was also caused by signalling failures in the Berrylands area. Work is already underway to improve infrastructure reliability, including a programme of LED signal head conversions over the next two years which is expected to support longer-term performance improvements.”
Actions to Remedy Failure:
- We are investing in improved technologies to provide remote visibility of fixed infrastructure (such as on train detection technology) 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.
Notice to Improve Performance
“A Notice to Improve Performance has not been issued by the Secretary of State in respect of this Performance Target Failure.”
