We are sorry that the Arterio rollout is taking longer than previously expected.
As has been well documented, as well as introducing a new set of trains, SWR is introducing a new method of work with our drivers responsible for opening and closing the doors (DODC operations). In order to do so, the drivers rely on effective CCTV cameras and in-cab displays down the full length of the 10-car train to make the judgement it is safe to depart. Many of the 98 stations the Arterio will serve were built more than 150 years ago, with the Victorian infrastructure creating some specific challenges in guaranteeing a consistently clear image for the driver, under all light conditions.
While we complete those works at our stations, we’ve taken the decision to re-phase our training programme in order to bring as many Arterios into customer service as quickly as possible. This means we will now begin training our Drivers and Guards to operate the trains with the Driver opening the doors and the Guards closing them (DOGC operations), which will enable us to operate on new routes sooner. SWR remains committed to returning to full DODC operations at the earliest viable opportunity.
With the shorter training programme now underway, the approach will enable an accelerated programme of introduction, with more Arterios to enter service as we approach the summer. We will share further details in due course.
While the further delay has been frustrating, we now have a way forward that will see increasing numbers of customers enjoying increased capacity and comfort of the Arterios through the rest of 2025 and beyond.
