[2] The line crosses the Basingstoke Canal at Mytchett Lake Railway Bridge[4][5] and the Windle Brook on the Guildford Road Viaduct.

[3][6] A 2017 infrastructure assessment commissioned by Surrey Heath Borough Council noted that rail journey times to London from Camberley are slow (c. 72 – c. 80 minutes) and that many local residents choose to drive to Brookwood, Farnborough (Main) and Sunningdale for faster, direct trains to the capital.

[13][14] At around the same time, a second similar scheme was proposed by the Sunningdale and Cambridge Town Railway (S&CT), which promoted a more southerly route, serving the new settlement of Camberley and terminating at a junction with the South West Main Line at Farnborough.

c. ccvii), passed by Parliament on 14 July 1864, authorised the eastern part of the S&CT line from Sunningdale to Camberley and £70,000 was raised to fund its construction.

[17] Construction began with a formal ceremony in November 1864, but after experiencing financial difficulties linked to the bank failure of Overend and Gurney, the company declared bankruptcy in 1866 and the work was abandoned.

[19][21][e] A contractor was appointed in 1874, but the works progressed slower than expected, meaning that the railway was not ready for its intended opening in 1877.

Goods yards were provided at the three intermediate stations[20] and the opening of the railway at Bagshot stimulated the growth of the plant nurseries in the area.

[23] On 2 June 1878, the single line to Ash Vale was opened and doubling of the track between Frimley Junction and station was completed.

[26] On 30 April 1938, the Surrey Border & Camberley Railway opened its southern terminus at Farnborough Green, close to Frimley station.

The 10+1⁄4 in (260 mm) narrow gauge railway closed at the start of the Second World War and did not reopen after the end of hostilities.

[27][28] Electrification of the Ascot–Ash Vale line was completed shortly before the start of the Second World War by the Southern Railway.

[36] The resignalling of the stretch of line between Camberley and Ascot was commissioned on 8 September 1974, with control of all train movements being transferred to Feltham.
