It was extended to Mansfield Woodhouse in 1995, with Kirkby-in-Ashfield station opening in 1996. The through passenger route from Nottingham to Worksop opened in 1998. In 2004, the section between Bulwell and Hucknall has been converted from double track to single track to allow space for the new Nottingham Express Transit tramway; this follows the route as far north as Hucknall and opened in March 2004. Service As of March 2020, the Robin Hood Line operates a Monday to Saturday service between 05:40 and 22:20. During the day, trains run at half-hourly intervals between Nottingham and Mansfield Woodhouse, with one service an hour continuing to Worksop, and the full journey taking 67 minutes. A Sunday service began on 7 December 2008, with ten trains running between Nottingham and Mansfield Woodhouse between 09:15 and 22:30. Four of those continued to Worksop. The Sunday service was funded by Derbyshire County Council and Nottinghamshire County Council. An understanding was made with the Department for Transport that, if the patronage reached an agreed threshold after two years, it would consider taking over the service and incorporate it within the East Midlands Trains franchise. However, this service was not a commercial success north of Mansfield Woodhouse, and Nottinghamshire County Council decided to reduce its funding and prioritise running a reduced Sunday service from 22 May 2011. The service runs eight times each Sunday between Nottingham and Mansfield Woodhouse and return. Proposed extension Just north of Shirebrook station is a junction with a freight branch line that was used for coal traffic to High Marnham power station via Warsop, Edwinstowe and Ollerton. Following closure of the power station the line is disused but has been kept open and fully maintained as a test track for driver training. In mid-2009 Nottinghamshire County Council commissioned a feasibility study to consider a plan to extend the Robin Hood Line along this route by extending the current hourly service between Nottingham and Mansfield Woodhouse to Ollerton, calling at Shirebrook, Warsop and Edwinstowe (for Center Parcs Sherwood Forest holiday resort). Nottinghamshire CC have remained keen on the idea, and met with the rail minister Claire Perry in March 2016 to press for the scheme to be adopted. The new line would be about long, but as much of it is used for driver training, only about of new track would be required, and the infrastructure is still in good condition. A
