Newspaper, The Age, "Trackless and with rubber wheels, it may be our next generation trams", 2/05/2021 12:00:00 AM
Newspaper clipping titled: “Trackless and with rubber wheels, it may be our next generation trams” by Timna Jacks Newspaper clipping from the Age 02/05/2021 Rubber wheels, electric batteries and no overhead wires could be the future for Melbourne’s trams. By 2025, 100 new trams will be designed and built due to a $1.5 billion government injection to fund 100 ‘‘next-generation trams’’, replacing A and Z-Class trams. Two manufacturers have been shortlisted to design and build the trams: French rail manufacturer Alstom and a joint venture comprising Spanish rail maker CAF and UGL. At 25 metres long – about eight metres shorter than the newest E-Class trams – the trams will carry 150 passengers, fewer than the E-Class, which carry 210 people. Despite the smaller size, seating will remain proportionally comparable with the E-Class, with 48 people or a third of passengers getting a seat on the new fleet. The new fleet will be the first in Melbourne to be partly powered by on-board batteries.trams, tramways, yarra trams, keolis downer, caf, rolling stock, e class, z class, a class, ugl, tramcar acquisition, tramcar design, tramcar manufacture -

Document - Interim Report - MMTB - Upon the General Scheme for the future development of Tramways in Melbourne and Suburbs, Melbourne & Metropolitan Tramways Board (MMTB), 1922
An interim report by the Melbourne and Metropolitan Tramways Board (MMTB) concerning the replacement of cable tramways in Melbourne, whose capacity was predicted to be incapable of coping with future demand. In light of some opposition to electrification via overhead wires, several schemes were outlined, including a conduit system, surface contact system, battery cars, petrol cars, petrol-electric cards, motor buses, and trolleybuses. In the conclusion, the MMTB asserted that all schemes other than overhead electrification are not optimal to serving the city, and remained committed to use overhead wires.A document that clearly shows the commitment of the now-superceded public transport agency (MMTB) to electrify the Melbourne tram network.Interim Report - MMTB - Upon the General Scheme for the future development of Tramways in Melbourne and Suburbspublic transport, mmtb, tramways, electrification, electricity -
