been the "Midnight Whistle", an evening function on 31 December of each year where members enjoy an evening meal and rare dusk and night time steam train rides. The site when everybody disembarks in a lineside field and the train reverses, prior to roaring past is memorable in itself. A lengthy blast on the whistle echoes around the local farms to signal in the New Year. The Society is registered under the Incorporated Societies Act 1908 and its Annual General Meeting is usually held in September and covers reports on activities of the society, annual election of all officers and committee members (incumbents, by the Society's constitution, must stand down at the beginning of the meeting) and discussions on future activities. Museum and office The Society's registered office is located at 38 Alfred Street, Onehunga, Auckland. Open Monday to Saturday, between 9:00 am and 12:00 pm, it is completely staffed by volunteer members of the Society. The office, not only takes excursion bookings, sells publications and answers all phone calls in relation to society and Glenbrook Vintage Railway activities, but also is the location where the Society's elected committee meets and Glenbrook Vintage Railway Charitable Trusboard and Branch meetings are held. It is thus, a very important piece of infrastructure for both entities. The building was built in 1873 and was originally sited on the corner of Princess St and Onehunga Mall, Onehunga, beside the Onehunga Branch. The tight curve at this point on the line resulted in the station platform having an irregular triangle shape. In 1964, the building was put up for sale and the society purchased it and moved it to the block of land it presently occupies – land designated for the future Avondale–Southdown Line. It is believed to be the oldest railway station building in the country. An F class locomotive, F 233, was displayed at the Office site until 1984 when it was moved to the Glenbrook Vintage Railway for eventual restoration. The building has also been used for a number of social events such as the Society's 30th and 40th birthday party (with accompanied rail excursion from Auckland City on both occasions), fundraising meals (in the lead up to Glenbrook Vintage Railway's opening) and smaller members meetings and overseas tour information meetings. The Railway Enthusiasts Society operates a museum out of the old Onehunga Railway Station, which includes a selection of railway photos,
