The existing Up line from Old Dalby to Melton Junction was retained at first, but after the end of activity at Old Dalby, it was cut back to Holwell Junction.

A Ground Frame known as Melton Ground Frame was installed south of Asfordby Tunnel at 106m 58c. The Up line north from Melton Ground Frame was left in and connected via a point to the Holwell Siding at Holwell Junction. This section of line was known as the "Up & Down Holwell Line".

The Up line south of Melton Ground Frame to Melton Junction was retained and was known as the "Up & Down Through Siding, Melton Junction Ground Frame to Melton Ground Frame". Melton Junction Signal Box was replaced by a Ground Frame in 1973.
