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. Mornington Opening on 23 March 1883, the Mornington line travelled up High Street to Mornington. This line was the steepest recorded tramline in the world, with a gradient at the highest point of the track measured at 1 in 3.75. The Mornington line was the last to close, on 2 March 1957, leaving San Francisco with the only operational cable car system in the world. Cable Car House (now used by the Mornington Health Centre after the Plumbers moved out) is still clearly marked in the shopping area, having had little external changes since the line closed. In 2013, a local group announced plans to reinstate this line. The project, estimated to cost $22m, would include a terminus near Mornington Park containing a cafe, museum and storage area for the cable car. Maryhill Extension The Maryhill Extension exited from the back of the Mornington cable car house at the end of Henderson St, following Glenpark Avenue for . The line was perfectly straight, and was sometimes referred to as The Big Dipper, similar to a roller coaster, going steeply down one side of the valley and then up the other side. It opened on 18 March 1885 and closed on 29 October 1955. The line was originally operated using two grip trams which were later destroyed by a fire. Later, the line was operated by the former Elgin Road grip tram, DCCT No 106. When this car was being overhauled, it would be replaced by 'convertible' grip tram No 105, which was used as a spare car on the Mornington and Maryhill lines as its grip could be set at two different heights to allow it to run on either line. Grip tram 106 was withdrawn in 1955 and donated to the Otago Early Settlers Museum where it remains on static display. 'Convertible' grip tram 105 remained in service on the Mornington line until the closure of the Mornington line in 1957 when it was donated in working order to the Seashore Trolley Museum in Kennebunkport, Maine, where it is stored in a complete state along with its grip.
