TransPennine Express (2016–2023)

TransPennine Express (TPE), legally First TransPennine Express Limited, was a British train operating company owned by FirstGroup that operated the TransPennine Express franchise. It ran regional and inter-city rail services between the major cities and towns of Northern England and Scotland.

The franchise operated almost all its services to and through Manchester covering three main routes. The service provided rail links for major towns and cities such as Edinburgh, Glasgow, Liverpool, Sheffield, Hull, Leeds, York, Scarborough, Cleethorpes, Middlesbrough and Newcastle upon Tyne. TPE ran trains 24 hours a day, including through New Year's Eve night. TPE trains ran between York, Leeds and Manchester Airport at least every three hours every night of the week. The franchise operated across the West Coast Main Line, Huddersfield Line, East Coast Main Line and part of the Tees Valley line.

The majority of TPE's rolling stock was procured during the late 2010s under Project Nova. These consist of the Nova 1 (Class 802) BMU trainsets, the Nova 2 Class 397 CAF Civity EMUs, and the Nova 3 Mark 5A fixed-formation carriages paired with Class 68 diesel locomotives. These replaced older rolling stock, such as the Bombardier Turbostar 170/3s and Siemens Desiro 350/4s, as well as some of their Siemens Desiro 185s, although these were still used on some routes. TPE had facilitated an operational shift towards more inter-city style services, although the commuter market remains important.

In May 2023, following a period of poor performance, it was announced that the company's contract would not be renewed and the service taken over by government-owned operator of last resort TransPennine Trains on 28 May 2023, who have continued trading under the TransPennine Express name. The decision to bring the service under the control of the operator of last resort was described as temporary, and it is said to be the UK government’s intention that the franchise will be privatised again.
