LNER will bring an InterCity 225 train back into service tomorrow as part of contingency plans to cover for reduced availability within its Azuma Class 800 fleet.

Hitachi Class 800 trains were withdrawn from service on Saturday for safety checks after cracks were discovered in part of the chassis of several trains.

LNER, which runs services between West Yorkshire and London, has introduced a revised timetable until Friday across its network, but is still managing to operate around three quarters of its planned timetable this week.

In recent years, the Azuma fleet has gradually been replacing the InterCity 225 trains on many East Coast Main Line services. The reduced timetable at the start of the Covid-19 pandemic saw more 225 trains - powered by Class 91 locomotives - placed into temporary storage until normal service levels resumed.

However, at least one of these trains - built over three decades ago - will be brought back earlier than anticipated to boost the LNER fleet.

In an updated statement issued tonight, an LNER spokesperson said: "A temporary, amended timetable will remain in place until Friday 14 May across the LNER route. This is due to a number of Hitachi Class 800 trains from several train companies being taken out of service for ongoing checks as a precautionary measure.

"The issue with the Class 800 trains continues to be investigated. Once trains have been checked, they are being reintroduced back into service as soon as possible. "In addition, LNER is due to introduce an InterCity 225 train back into service tomorrow ahead of the original reintroduction date planned for June.

"Customers are being asked to check before they travel and ensure they have a seat reservation. We apologise for any disruption caused. The latest information can be found at lner.co.uk.”
