Hi the NR ballast cleaning set is being used and stored at tuxford. The line between Thoresby Junction and High marnham powerstation is being used as a new test track. Since November 2009 and for the next few months the line will be under possesion for ballast cleaning works, track replacement and for new crossovers/points to be introduced to increase line speeds upto 70mph. Soon the work will also include the currently operational section of line between Shirebrook and Thoresby Colliery which will see the coal trains using single line working as work will be carried out on the second line.
Also work to reinstate the Bevercotes colliery branch may begin sometime at the close of 2010.
At the site at Tuxford, near to the A1, 1 set of wagons and the main ballast cleaning unit is stored there everyday and is only moved usually between 8-4 Monday to Friday. The other set is stored at the site usually over the weekend unless it is needed on engineering works elsewhere. During the week, the set is brought in from toton at around 7am. Normal traction on the line is DB schenker class 66 top and tail. Class 60's and class 37's can be seen on occasions.
Hope this helps. Any other questions and ill try and help.
