The section to Melton follows the former railway from Nottingham to Melton, now the Old Dalby Test Track, and to the A46 junction is only a few hundred metres apart.
Testing of the first batch of new units, the 172/0 sets for London Overground, commenced in March 2010, with two sets (anonymous as they did not have unit numbers on them) being tested on the Old Dalby Test Track.
Just outside Melton Mowbray station the main line is joined by the Old Dalby Test Track.
Old Dalby is the location of the control centre of the former British Rail Research Division's railway test track, which runs between Melton Mowbray and Edwalton and which was universally known in the industry as simply 'Old Dalby'.
In April 2010, the track was used by Class 172 diesel multiple units, also manufactured by Bombardier in Derby.
The station is now closed, although the line still exists today as the Old Dalby Test Track.
