Background Information:

Network Rail are upgrading the Overhead Line Equipment (OLE) between Luton North and Bedford. The wiring is being upgraded on this part of the Midland Main Line so that East Midlands Railway’s new greener fleet of bi-mode trains will be able to travel at up to 125mph on this section of the line. Head spans and some other OLE components that are life expired will also be replaced.

These improvements will ensure smoother and more reliable journeys for passengers travelling between South Yorkshire, the East Midlands, and London. More details on this project can be found on the Network Rail website.

Replacement Bus Travel Advice:

For helpful advice if you need to travel on a rail replacement service, including accessibility and bicycle information, please use our Rail Replacement Services page.

You can find the pick-up and set-down location of rail replacement services by checking station signage or by searching for your station on our Find a Station page.

Please be advised that replacement vehicles may be busier than usual, and you should allow extra time for your journey.
