The station was designed by the Midland Railway company architect John Holloway Sanders.

Following the closure of the line as a through-route in 1968, the track between Melton Mowbray and Edwalton was converted for use as the Old Dalby Test Track, used initially for the Advanced Passenger Train project and, more recently, for Class 390 Pendolino units.

Old Dalby was the site of the original control centre for the line in BR days equipped with utility buildings and a small workshop.

Today there are still sidings at Old Dalby and an enlarged workshop and new track layout to accommodate the London Underground trains on test.

The station master's house survives by the roadside as a private residence and the weighbridge as a domestic garage.
