Network Rail assessing impact of Grand Central's plan for bi-mode trains on East Coast Main Line

Network Rail is carrying out power modelling to assess the impact of Grand Central using overhead line equipment to power a potential fleet of new trains on the East Coast Main Line (ECML).

The open access operator has said it anticipates ordering a fleet of five-car bi-mode units to replaces its Class 180 DMUs if its existing rights between London King’s Cross, Bradford Interchange and Sunderland are extended until 2038 by the Office of Rail and Road.

If ordered, the trains would be introduced throughout 2028.

Responding to the request, Network Rail (NR) said the ECML has known power constraints. Power modelling started in late 2024, with NR’s letter in early December saying that was expected to be finished in January.

Mark Garner, Customer Manager for Eastern Region at NR, wrote: “The outputs of the power modelling will determine where Grand Central can utilise electric running (and expected faster performance) and whether Network Rail requires a footnote added to Grand Central’s right…so that all or part of their service(s) can only run with diesel traction.”

Early modelling outputs were shared with Grand Central on November 21.

In response, Grand Central’s Interim Director, Chris Brandon, said: “Our understanding of the initial results is that when considered in isolation, GC services could be accommodated within the existing power supply capacity.”

Garner said NR also wanted clarification on where the new services will be maintained and confirmation of train lengths. Grand Central’s reply said trains would continue to use the same site for stabling trains in London, West Yorkshire and the North East, and that the five-car trains would be a “similar size” to those already operating on the ECML.

ORR has also asked Grand Central for evidence on its plan to invest in new rolling stock to justify the 11-year extension from 2027 to 2038. The Railways (Access, Management and Licensing of Railway Undertakings) Regulations 2016 says justification must be provided for access contracts longer than five years.

An ORR spokesman said the regular plans to make a decision “promptly” once it receives the necessary evidence.
