GWR boss calls for electrification to Swansea and faster train speeds in Wales

Mark Hopwood said his trains travel at 125mph but cannot do so in Wales

The boss of train company Great Western Railway (GWR), Mark Hopwood, has called for electrification of the South Wales mainline to reach Swansea alongside investment allowing his trains to travel at much higher speeds once through the Severn Tunnel.

Electrification of around 60 miles of track from Cardiff to Swansea was shelved by then º£½ÇÊÓÆµ Government Transport Secretary Chris Grayling back in 2017 on cost grounds. With the whole electrification of the Great Western Mainline starting from London over budget and running overtime, there were even, at one stage, concerns that it would only go as far as Bristol.

The managing director of GWR, whose franchise covers services on the South Wales to London route, said electrification to Swansea would have operational as well as environmental benefits. GWR’s Hitachi bimode trains on the route have to run in diesel mode between Cardiff and Swansea, while operating in less polluting and more efficient electric mode on the rest of the route.

Trains on sections of the route in England can reach speeds of 125mph. However, once on the Welsh side of the Severn Tunnel they have to operate at average speeds well below 100mph.

To improve line speeds will require a series of problem fixes, including addressing curves in the line, the removal of some level crossings and more use of relief lines to separate local train traffic from GWR and other cross-border services. As the line is not devolved it would need funding from the º£½ÇÊÓÆµ Government.

Line speeds

To get Treasury approval the business case for electrification to Swansea, and line speed improvements, might have to be wrapped up into a much bigger scheme, taking in the proposed Cardiff Crossrail project, and the goal also of increasing services from West and South Wales to Bristol, which are currently just at two an hour. There are six between Manchester and Leeds.

Giving evidence to a Welsh Affairs Committee probe into Welsh rail infrastructure, Mr Hopwood told cross-party MPs: “Clearly as a railway person, having spent all my working life in it, I believe in the railway and I would like to see more investment.

“I have got a train on the London route that can travel at 125mph, but once it enters the Severn Tunnel, it will never reach 125mph again in Wales.
