Dunedin cable tramway system

The Dunedin cable tramway system was a group of cable tramway lines in the New Zealand city of Dunedin. It is significant as Dunedin was the second city in the world to adopt the cable car (the first being San Francisco).

The first Dunedin cable car line opened in 1881, the engineer responsible being George Smith Duncan. For this system he introduced the pull curve and the slot brake; the former was a way to pull cars through a curve, since Dunedin's curves were too steep to allow coasting, while the latter forced a wedge down into the cable slot to stop the tram, which was deemed necessary after the line had a runaway tram some two months after it opened.

The last line closed on 2 March 1957.

Dunedin's first cable car served Roslyn (although initially only going as far as the town belt), covering a distance of 1.4 miles (2.3 km), opening on 6 February 1881. The line went up Rattray Street, with the world's first pull curve in front of St Joseph's Cathedral. It then cut through the Town Belt in Belleknowes (where the cutting is still generally visible) past the Beverly-Begg Observatory to climb the full length of Ross Street and part of Belgrave Crescent, then descend through a cutting to the valley near Frasers Road.

The last cable car ran on this line on 25 October 1951.

The western section beyond the cutting was too steep for a road link, so, when the cable cars ceased, the portion near Belgrave Crescent was redeveloped as a short street serving several houses while retaining the pedestrian walkway through to Delta Street. Trolleybuses replaced the service as far as Belgrave Crescent, using City Road instead of the straight steep cutting through the Town Belt.

Travelling a distance of 1.2 miles (1.9 km), the Stuart Street line opened on 6 October 1900, running largely parallel to the Roslyn line. The track went up Stuart Street from The Octagon, turned half-right at York Place into what was then called Albert Street, continued on past the end of that street through a short section of Town Belt, past Otago Boys' High School, across the bottom of Littlebourne Crescent and up to Highgate at School Street, then dropped down to Kaikorai just before Nairn Street, where a turntable in the road turned cars through 90° and sent them south-west into their shed. The route was eventually turned into a four-lane highway, cutting Littlebourne Crescent off from Littlebourne Road, going under a new bridge and undergoing considerable widening on the Kaikorai side, restricting access to Ann Street and Oates Street. It closed on 31 July 1947.
