Notes: The York and North Midland Railway opened in 1839, connecting York with the Leeds and Selby Railway and in 1840 with the North Midland Railway at Normanton near Leeds. The line was largely financed by George Hudson who invested a substantial inheritance in the North Midland, becoming a director. He then took an active part in the promotion of the route and commissioned George Stephenson to construct the line.

Having completed the York line, George Hudson turned his attention to Harrogate, proposing a branch to the town from a junction with the Y & NM at Normanton with stations at Stutton, Tadcaster, Newton Kyme, Thorpe Arch, Wetherby and Spofforth and a terminus at Harrogate. Local people and businesses initially opposed the railway fearing an influx of people from Leeds and Bradford would lower the tone of the area but this opposition was overcome and the line opened to a temporary terminus at Spofforth

10th August 1847 and was extended into Harrogate Brunswick on 20th July 1848. The terminus was sited on Trinity Road, adjacent to the Methodist church opposite The Stray and was constructed entirely of timber. The main engineering features were at the north end of the route between Spofforth and Harrogate with the line passing first through the 825-yard Prospect tunnel then across the 31 arch Crimple viaduct and then through the 400-yard Brunswick tunnel before entering the terminus at Harrogate Brunswick. (This was the official name of the station although in timetables it was only shown as Harrogate).

On 1st September 1848, the Leeds and Thirsk Railway (renamed Leeds Northern Railway in 1849) opened their line to Harrogate with a station to the east of the town at Starbeck. In 1849 George Hudson was forced to resign as chairman of the York & North Midland Railway following his involvement in dubious business activities.

In 1851 the Thirsk line was joined by the East and West Yorkshire Junction Railway from York at Knaresborough east of Harrogate.  In 1854 the York & North Midland Railway amalgamated with the Leeds Northern Railway to form the North Eastern Railway who built a new line from a junction with their Normanton line immediately south of Brunswick tunnel; this allowed trains to run into Starbeck station.

A new central station was opened at Harrogate on 1st August 1862 and Brunswick Station was closed. Initially the terminus was retained for goods traffic but this was short lived.  The exact date of final closure is not known but the 1893 Ordnance Survey map shows the track in the southern approach cutting to the tunnel had been lifted and the cutting to the north of the tunnel has been infilled..

Brunswick tunnel found a new use during WW2 when an air raid shelter was built just inside the north portal; it was the only large public shelter in that part of Harrogate. Harrogate was only bombed once in 1941 and that was in error when one German plane strayed over the town. The shelter was abandoned by 1943 and sealed.  In c1954 the tunnel was surveyed for possible use by the Ministry of Supply as an engineering works but it was never used for this purpose.  All evidence of the shelter entrance was finally removed in the 1960's during road alterations. At this time workmen accidentally dug into the tunnel roof unaware of its existence!

Today the only evidence of Brunswick station is a metal commemorative plaque mounted on a stone at the site. No photographs of the station are known.
