[2] The Leeds Northern Railway (LNR) extended their line from what would become Melmerby Junction to Stockton via Northallerton, which opened in June 1852 with Northallerton Town opening on the same day as the line.

[3] The two lines ran parallel to each other but at different levels, with the YN&B running on an embankment to the east of the LNR.

The LNR line was routed under the YN&B just north of Northallerton station with the LNR station located on the north-eastern edge of town where the Low Gates level crossing still is.

[5] In July of the same year, the two companies (and one other, the York & North Midland) amalgamated to form the North Eastern Railway and in January 1856, a new spur was opened between the Leeds Northern Line and the high level Northallerton station, making Northallerton Town railway station redundant.

[4] The station was retained for goods traffic[6] with it being reduced to a public delivery siding in 1968.
