Melbourne tram route 109 is operated by Yarra Trams on the Melbourne tram network from Box Hill to Port Melbourne. The 19.3 kilometre route is operated out of Kew depot with A and C class trams. History The origins of route 109 lie in separate tram lines, a cable tram from Spencer Street to the Yarra River, a horse tram from the Yarra River to Kew Cemetery, an electric line from Kew Junction to Box Hill (extended over the years), as well as the Port Melbourne railway line. A cable line was opened by the Melbourne Tramway & Omnibus Company from Spencer Street to Brunswick Street along Collins Street, MacArthur Street, Gisborne Street and Victoria Parade on 2 October 1886, and extended to the west side of the Yarra River along Victoria Parade and Victoria Street on 22 November 1886. A connecting horse tram was built from the east side of the Yarra River to Kew Cemetery, along Barkers Road, High Street South and High Street, opening on 28 December 1887. The Prahran & Malvern Tramways Trust (PMTT) opened a line from High Street to Burke Road along Cotham Road on 30 May 1913. On 1 November 1914 the PMTT received permission to convert the horse tram line to electric traction, and the new electric line was opened on 24 February 1915. The PMTT extended the Cotham Road line to Union Road, Mont Albert along Whitehorse Road, on 30 September 1916. In 1929 the Melbourne & Metropolitan Tramways Board (MMTB) started converting the Collins Street cable lines to electric traction, with the last cable tram running down Collins Street on 14 September 1929, and the first electric tram on 8 December 1929. At the same time the MMTB built a new electric line down the centre of Victoria Parade to replace the cable line, which opened on 15 September 1929. For the next six decades the Melbourne to Mont Albert tram was numbered 42, celebrated by a 1982 theatrical production, Storming Mont Albert by Tram, which was performed on a specially-chartered Route 42 tram from the Mont Albert terminus to the city and return. The line was extended south-west to Port Melbourne along Spencer Street and the former Port Melbourne railway line on 21 December 1987 following the conversion of the railway (along with the St Kilda line) to light rail. The broad gauge track was re-gauged to standard gauge
