Could HS2 Trains Continue To Wales?
The title of this post is the same as that of this article on New Civil Engineer.
This is the sub-heading.
North Wales business group Growth Track 360 has recently renewed its calls for electrification of the North Wales Main Line to accommodate HS2 trains.
These two paragraphs add some more detail.
The group is pushing for electrification of the North Wales Main Line to Crewe and Warrington, which would allow HS2 trains to run directly from London and Birmingham to Chester and beyond.
It has also commissioned a series of conceptual artworks to help the public visualise the proposed improvements. Produced by Nataliia Marchuk, a Ukrainian Fine Arts undergraduate at the University of Chester, the first shows an HS2 train passing Conwy Castle on an electrified North Wales Main Line.
The article dates from May 2022, so it is a bit old now, but transport in Wales is moving on.
On the Growth Track 360 web site, I found this mission statement.
Growth Track 360 has been launched to secure £1bn of rail improvements, which would transform the North Wales and Cheshire regional economy and deliver 70,000 new jobs over 20 years.
It’s being led by a cross-border alliance of business, political and public sector leaders.
If successful, it would lead to a massive boost to the North Wales, Cheshire and Wirral economies, linking them with the planned HS2 line between London and the North of England.
This OpenRailwayMap shows the railways in the area.
Note.
- The lilac tracks are Merseyrail’s third rail network.
- The lilac knot in the North-West corner of the map is the city of Liverpool.
- The red tracks are electrified with 25 KVAC overhead and connect Liverpool to Manchester in the East and Crewe in the South-East corner of the map.
- The black tracks are not electrified.
- The blue arrow marks the position of Chester.
- The lilac line going North from Chester is the Borderlands Line to Liverpool.
- Chester and Crewe are a distance of just over twenty-one miles.
Looking at the route on Google maps, I don’t think to electrify between Crewe and Chester will be the most difficult of projects.
The Advantage Of Electrifying Between Crewe and Chester
In How Far Will A Class 897 Train Travel Without Using The Electrification?, I showed that that these new tri-mode trains have a range of 120 miles.
In The Data Sheet For Hitachi Battery Electric Trains, I look at the data sheet, that Hitachi published in late 2023.
These were my conclusions about the data sheet.
These are my conclusions about Hitachi’s battery packs for Class 80x trains, which were written in November 2023.
- The battery pack has a capacity of 750 kWh.
- A five-car train needs three battery-packs to travel 100 miles.
- A nine-car train needs five battery-packs to travel 100 miles.
- The maximum range of a five-car train with three batteries is 117 miles.
- The maximum range of a nine-car train with five batteries is 121 miles.
As battery technology gets better, these distances will increase.
Hitachi have seen my figures.
They also told me, that they were in line with their figures, but new and better batteries would increase range.
It looks like Great British Railways will have at least two 125 mph, 120 mile range express trains away from the wires.
These are distances from Chester.
- Holyhead – 84.4 miles
- Bangor – 59.7 miles
- Llandudno Junction – 44.7 miles
It would appear that electrifying between Crewe and Chester will be an insurance policy to make sure, that battery-electric trains can serve Holyhead.
Electrifying between Crewe and Chester, will also ensure, that any battery-electric train leaves Chester with a full battery.
Are There Any Battery-Electric High Speed Trains?
I asked Google AI, this question and received this answer.
Yes, battery-electric high-speed and intercity trains are entering service, primarily in Europe. While many battery trains are designed for regional speeds, Hitachi Rail offers intercity battery trains capable of high speeds and over 70 km ranges. In 2026, the UK’s Great Western Railway (GWR) launched a record-breaking, fast-charging battery train with a 200-mile range.
Key Developments in Battery Trains:
Hitachi Rail Intercity Battery Trains: These trains can operate at intercity speeds, designed for both electrified and non-electrified routes, enhancing sustainability without sacrificing performance.
GWR Class 230 Battery Train: This UK-based, three-car train achieved a world record of over 200 miles on a single charge in 2025.
Rapid Charging Technology: The GWR train uses a 2,000kW fast charger, allowing it to recharge in just over three minutes while stopped at a station, making it suitable for extending electrical service without full, expensive track electrification.
Regional Battery Trains: Beyond the UK, Hitachi’s battery trains (Full battery, Hybrid, Tri-brid) are part of a broader shift in Europe toward lowering emissions. In Argentina, battery-electric units are also used for regional services, designed to operate with solar-powered charging.
These developments show a move towards using battery technology to reduce reliance on diesel trains on partially electrified lines.
How Long Will HS2 Take To Go Between London Euston And Holyhead?
Consider.
- Sources like the House of Commons Library give HS2 times of 56 minutes between London Euston snd Crewe.
- Avanti West Coast’s Class 805 trains take two hours and two minutes between Crewe and Holyhead.
I don’t think that a sub-three hour journey is unreasonable.
Is A Green Route Between London And Dublin Possible?
As we’re more likely to see a zero-carbon ferry, than a zero-carbon airliner. Yes!
