the suburb. This end of the suburb is dominated by one of Dunedin's largest industrial sites, the Hillside Railway Workshops. At the western end of the suburb, the valley rises steeply, culminating in a saddle of the motorway at Lookout Point. From here, there are views over the outer suburbs of Burnside, Green island, and Abbotsford. Caversham's 2001 population was 5,019. Mornington, Maryhill, and Balaclava Due west of the city centre, with primary access up High Street, sits the hill suburb of Mornington. Southwest of it is Maryhill, while Balaclava is a small locality to the west of Maryhill. Mornington was originally served by a cable car from The Exchange, with a connecting line running from Mornington to Maryhill. Maryhill takes its name from a district in the city of Glasgow in Scotland, due to settlers from Maryhill in Scotland many years ago. Roslyn and Belleknowes The suburb of Roslyn lies atop a crest which forms part of the inner ring of hills around Dunedin. Excellent views of the inner city can be gained from the Roslyn overbridge, which is 1,500 metres northwest of the city centre, and 150 metres above sea level. Several of the city's most prestigious schools are located close to this suburb and its northern neighbour, Maori Hill. Its southwestern end merges imperceptibly into Belleknowes. Roslyn's 2001 population was 3,957. Maori Hill and Prospect Park Along with St Clair, Maori Hill is regarded as one of Dunedin's more exclusive suburbs. Many fine houses are located among the trees of the city's Town Belt, which snakes around the slopes of the crest which surrounds much of the inner city. Unlike neighbouring hill suburbs like Roslyn, Maori Hill was not served by a cable car, possibly underlying its greater degree of exclusivity. Maori Hill's 2001 population was 1,956. Prospect Park, a small suburb centred on the park of the same name, is sited at the northern end of the ridge which runs through the hill suburbs south to Lookout Point, overlooking the broad canyon of the Leith Valley. Woodhaugh, Glenleith, and Leith Valley At the northeastern end of the coastal plain that makes up the central city area, the Water of Leith forms a valley leading between Maori Hill and Pine Hill. In its lower reaches, this valley is broad, and is dominated by Woodhaugh Gardens. Much of Dunedin's water supply comes from reservoirs in the upper reaches
