High Speed 2 is to start preparatory works for the future electrification of a 25km section of the Midland Main Line which will used by HS2 trains in phase 2b.
The section from Clay Cross to Sheffield will be used by HS2 as part of a spur into the city via Chesterfield.
Last year transport secretary Chris Grayling scrapped plans to electrify the entirety of the line, prompting fears that the electric only HS2 trains would not be able to use the line. In a subsequent announcement he then clarified this would not be the case.
Grayling has now asked that this section be included in the hybrid Bill for HS2 phase 2.
HS2 will begin its preparatory works with a series of land surveys to further inform the work programme.
A public consultation on the works required for electrification will be undertaken at a later date, it said, prior to the hybrid Bill being brought to Parliament.
An HS2 spokesperson said: “The benefits that HS2 will deliver are significant and should not be underestimated. The new railway will play a crucial role in rebalancing Britain’s economy; driving business growth, creating jobs and securing investment right across the country.
“Ensuring the Midland Main Line is electrified between Clay Cross and Sheffield Midland Station will enable Chesterfield and the wider Sheffield City Region to benefit from direct services on the new high speed trains.”
