The cache is hidden just outside of the station grounds, in a place where it should be easy to retrieve and replace. As of May 2016, the new location doesn't offer the previously advertised view of Alexandra palace, but should be a bit safer for the cache. If you want to see the view, just cross the footbridge and take a few steps up the road to the left.
The New Southgate station was opened in 1850 on the Great Northern Railway's main line to Peterborough and was originally intended primarily to serve the Colney Hatch Lunatic Asylum which was being built at the time. Later known as the Friern Hospital, the asylum has since been developed into luxury flats. The opening of the station came as the turning point for the whole area. Entirely undeveloped, with only two groups of farm buildings nearby, the station brought new life into the area, and by 1867 the core of New Southgate had been built. Ironically, the connection with the Asylum impeded further development because the middle classes could not be persuaded to live so near to the lunatic asylum. Attempts to remedy this can be seen in gradual changes of the station's name. Originally called Colney Hatch, the station was renamed Southgate and Colney Hatch (1855), New Southgate and Colney Hatch (1876), New Southgate for Colney Hatch (1883) and finally New Southgate and Friern Barnet (1923).
Nowadays, approximately 500,000 commuters use the station every year, and on average 3 trains per hour to Moorgate and 3 trains per hour to Welwyn Garden City stop at the station during off-peak times.
