The overhaul is taking place at the train operator’s Shields Road Depot in Glasgow.
The 38-strong fleet of trains consists of 130 carriages and is ScotRail’s second largest fleet of electric trains.
Class 380s were introduced to Scotland’s Railway in December 2010, operating in Ayrshire and Inverclyde initially, but now serve customers on routes across the country, including:
Glasgow Central – Edinburgh via Carstairs
Glasgow Central – Ayr
Glasgow Central – Largs / Ardrossan Harbour
Glasgow Central – Gourock / Wemyss Bay
Edinburgh – North Berwick / Dunbar
Syeda Ghufran, ScotRail Engineering Director, said:
“Since their introduction, our Class 380 trains have been incredibly popular with customers right across the country.
“This work to refresh their interior demonstrates our commitment to delivering the highest quality service, and helps make rail travel a more modern, comfortable and popular option for customers.”
Steve Timothy, Eversholt Rail Stakeholder Director, said:
“We are delighted to continue working in partnership with ScotRail to improve our fleets in Scotland.
“Our investment in the overhaul of the Class 380 fleet demonstrates our commitment to delivering safe and high-quality trains to our customer and their passengers.”
