This spur was the remnants of the Kingsport Subdivision, known locally as the CVR (Cornwallis Valley Railway).

It was created on January 31, 1961 when the subdivisions north of Kentville, the Kingsport Subdivision and Weston Subdivision were abandoned, reducing the branchline to a spur from Kentville to Mill Village (Steam Mill).

September 22, 1993 - CP Rail formally abandons the Halifax Subdivision from New Minas (mileage 52.9) to Kentville (mileage 56.1), including the 4.3 mile Kentville Spur from mileage 56.1 of the Halifax Subdivision to the end of track in Coldbrook, as well as the 2.3 mile Kingsport Spur from mileage 56.1 of the Halifax Subdivision to the end of track in Mill Village (Steam Mill).
