LNER inherited a fleet of InterCity 125 and InterCity 225s from Virgin Trains East Coast (VTEC).
Since September 2016, VTEC had hired three Class 90s from DB Cargo for use on services to Newark, York and Leeds.
LNER inherited these locomotives and retained them until June 2019 to cover for the shortage of Class 91 locomotives.

In May 2019, the first lot of Class 800 trains began entering service with the Class 801 trains also following on in September.
These units are based on the Hitachi A-train design and LNER retained the Azuma brand for the units which was originally designated by VTEC.
The initial operation of these units allowed the InterCity 125 and InterCity 225 fleets to be replaced gradually.
The first Azuma train to enter service was a 9-carriage 800/1 on 15 May on the Leeds route from King's Cross.
Other subclasses of the 800 and 801 variants entered service afterwards, with the first two 5-carriage 801/1 sets entering service on 16 September operating as a 10-carriage train, the first lot of 5-carriage 800/2 sets entering service to coincide with the launch of the new King's Cross - Lincoln services on 21 October and the first two 9-carriage 801/2 sets entering service on 18 November.
This means the whole Azuma class has entered service, but not all units are ready for service yet.

Following the withdrawal of the InterCity 125 fleet in December 2019, it was previously thought that the InterCity 225 fleet would be fully withdrawn by June 2020.
However, LNER announced on 29 January 2020 that they would be retaining a limited number of the InterCity 225 fleet to deliver all of the benefits of their December 2021 timetable.
LNER later confirmed that they would be keeping 10 sets in service.
