Alstom’s first G Class tram enters service in Melbourne

Melbourne’s first G Class tram has entered passenger service on Route 59, marking a major milestone in the city’s next-generation fleet program and adding a new locally built model to the world’s largest operational tram network.

A low-key launch for a long-anticipated fleet

Reports from local transport observers indicate that the first G Class tram quietly carried its first paying passengers in late July 2026, following months of testing from the new Maidstone tram depot. Early services have been operating on Route 59 between Airport West and the central city, giving commuters a first look at the new three-section, low-floor design.

The start of G Class operations follows a multi-year procurement and manufacturing program backed by the Victorian Government’s order for 100 next-generation trams and the construction of the Maidstone depot in Melbourne’s inner west. Publicly available information from government transport updates shows that the new fleet is intended to progressively replace older high-floor trams and boost capacity on key corridors in the city’s north and west.

Unlike previous high-profile rollouts on the network, coverage of the first G Class service suggests that the introduction was deliberately low key, with regular passengers sharing images and timing details on social media rather than through a formal launch event. Enthusiasts tracking the rollout describe the first runs as part of a carefully managed introduction that limits crowding while crews and maintenance teams gain experience with the new vehicles in day-to-day conditions.

The first tram to enter service is part of a broader test and acceptance program that has seen units delivered by road from Alstom’s Dandenong factory to Maidstone since late 2025. Industry briefings and technical documents describe the G Class as entering “revenue service” only after extensive trial running and certification on the existing Yarra Trams network.

Designed for accessibility, capacity and comfort

According to publicly released project material, the G Class has been developed as a fully low-floor tram based on Alstom’s Flexity 2 platform, customised for Melbourne’s street-running network. Official design information highlights wider doors, level boarding at compatible platform stops and spacious internal layouts intended to improve accessibility for passengers using mobility aids, prams and luggage.

The new trams are longer than many of the legacy high-floor vehicles they will eventually replace, increasing overall capacity on some of Melbourne’s busiest corridors. State transport fact sheets outline features such as improved passenger information systems, modern heating and cooling and energy-efficient traction systems designed to reduce power consumption compared with older fleets.

The G Class interior design has been informed by earlier community engagement, with feedback on seating layouts, handrails and standing space collected during mock-up displays. Project summaries indicate that these consultations aimed to balance comfort for seated passengers with the need to accommodate higher standing loads during peak periods, particularly on lines serving rapidly growing suburbs.

Accessibility advocates have long pointed to the gap between Melbourne’s extensive tram network and the number of stops that are fully accessible. The arrival of the G Class intensifies focus on stop upgrades, as the low-floor vehicles can only provide step-free boarding where platform or safety-zone stops meet current standards.

Maidstone depot anchors the next-generation program

The new Maidstone tram depot is central to the introduction of the G Class, providing stabling, maintenance and operations facilities purpose-built for the larger low-floor fleet. Government project documentation describes the site as a modern, energy-efficient facility with capacity for up to 30 G Class trams, including heavy maintenance workshops and cleaning facilities.

Construction updates show that the depot was largely completed in late 2025, enabling the first G Class units to be delivered for testing on nearby tracks before moving onto the wider network. Alstom has a long-term maintenance role at Maidstone under the supply agreement, with the depot serving as the operational hub for the new fleet.

The location in Melbourne’s inner west reflects the initial deployment plan, with early G Class services slated for routes 57, 59 and 82 that operate from depots and corridors in the region. Over time, government planning material indicates the depot will support broader service changes, including potential reallocations of older low-floor trams to other parts of the network as the G Class fleet grows.

The investment in Maidstone forms part of a wider rolling stock and infrastructure package across Victoria, including Alstom’s X’Trapolis 2.0 suburban train program and upgrades to signalling and power systems. Together, these projects are positioned as renewing key parts of Melbourne’s public transport fleet while sustaining local manufacturing and engineering capability.

Network impacts and staged rollout across routes

Planning information from Transport Victoria shows that the G Class trams are scheduled to appear first on routes 59, 57 and 82, with later expansion to routes 12, 48 and 58 as more units enter service. The choice of Route 59 for the initial passenger operations reflects both strong demand and the availability of upgraded stops suitable for the longer low-floor vehicles.

Discussion among passengers and enthusiasts highlights that infrastructure readiness is a determining factor in how quickly the new trams can be rostered onto additional lines. Many stops on Route 57 and parts of Route 82 still require lengthening or rebuilding to safely accommodate the longer trams, as shorter safety zones and platforms would otherwise prevent doors from aligning fully with boarding areas.

Government project pages note that a rolling program of stop upgrades is under way in Melbourne’s north-west to meet accessibility standards and prepare for G Class operations. These works include platform extensions, improved shelters and lighting, and revised road layouts at some intersections to manage the longer vehicles and maintain traffic safety.

Transport planners expect the higher capacity of the G Class to ease crowding on key corridors once a sufficient number of vehicles is in service. Over time, the new trams are intended to support timetable changes, with the potential for increased frequencies or longer operating spans on some routes as fleet reliability and maintenance regimes at Maidstone are refined.

Local manufacturing and broader mobility strategy

The G Class project has been framed by public information as a significant boost for local industry, with Alstom’s Dandenong site responsible for manufacturing the 100-strong fleet. Victorian Government announcements have previously highlighted the number of direct and indirect jobs associated with the program, including roles in fabrication, component supply and maintenance.

The tram order sits alongside other major contracts awarded to Alstom in Victoria, such as the X’Trapolis 2.0 train fleet and signalling work on the Metro Tunnel and regional lines. Together, these projects represent a long-term commitment to onshore production and technology transfer, reinforcing Dandenong’s role as a major rail manufacturing hub in the southern hemisphere.

For passengers, the entry of the first G Class tram into service is one of the most visible signs of that broader strategy, alongside the recent rollout of the new train fleet on suburban lines. As additional G Class units join regular operations over the coming months, Melbourne’s tram network is expected to show a steadily increasing share of modern, accessible vehicles.

Observers of the rollout note that the success of the G Class program will ultimately be judged on everyday performance: reliability in peak periods, comfort levels during crowded trips and the ease with which passengers can move between different parts of the multimodal network. With the first tram now carrying passengers, Melbourne has entered a new phase in testing those ambitions on the streets.
