From May 2003 until September 2004 Midland Mainline operated an hourly service between St Pancras and Manchester Piccadilly at the request of the Strategic Rail Authority whilst the West Coast Main Line between London Euston and Manchester underwent engineering work using former Virgin CrossCountry High Speed Trains [REF].
The service used the Midland Main Line as far as Trent Junction, before taking the Erewash Valley Line (avoiding Derby) to Clay Cross, rejoining the Midland Main Line until Dore South Junction, using Dore Tunnel Curve to join the Hope Valley Line westwards towards Manchester Piccadilly.
