From Derby to Dundee: ScotRail to replace HSTs with 222s


A fleet of diesel trains built for the Midland Main Line in England more than 20 years ago is going to Scotland, where it will replace ScotRail’s High Speed Trains.

The HSTs, which entered service during the later 1970s, are the last of their type in regular service in Britain, after GWR retired its four-car ‘Castle’ sets in December last year.

The Class 222s ordered by the Midland Mainline franchise and introduced in 2004 were based on the existing Voyager trains built by Bombardier, and were named ‘Meridians’.


Although they looked similar to the Voyagers, their internal layout was redesigned.

Bombardier’s successor Alstom has won a £250 million technical support contract for the 22 five-car units which will run until March 2036, with an option for a six-year extension. 

A separate £80 million contract with owners Beacon will provide new seating, tables, carpets, LED lights, upgraded cabs, toilet refurbishments and better luggage and bicycle areas. Accessibility will also be improved.

The Scottish Government is contributing £67 million, and the first of the 222s should enter service later next year, with all 22 sets in service by the end of 2028.

ScotRail managing director Joanne Maguire said: ‘This is fantastic news for our customers and our staff, as we continue to work towards delivering a safe, green, and reliable railway.  

‘More modern trains are a significant factor in encouraging more people to leave the car at home and travel by rail, and this investment will deliver a considerable improvement in the journey experience.  

‘Introducing fully refurbished trains ensures customers will see immediate benefits, with enhancements in comfort, accessibility, and reliability. 

‘We are looking forward to working with our partners and the Scottish Government in the coming weeks and months as we begin the refurbishment programme and get set to welcome this fleet to ScotRail.’
