The B-class Melbourne tram is a class of two-section, three-bogie articulated class trams that operate on the Melbourne tram network. Following the introduction of two B1-class prototype trams in 1984 and 1985, a total of 130 B2-class trams were built by Comeng (later ABB), Dandenong.

They were developed for the conversion of the St Kilda and Port Melbourne railway lines to light rail, and introduced by the Metropolitan Transit Authority, and later the Public Transport Corporation between 1984 and 1994.

History

[edit]

In preparation of the conversion of the St Kilda and Port Melbourne railway lines to light rail, two prototype B1-class trams were built in 1984 and 1985 at the end of an order for A1-class trams.[2][4][5] They were followed by 130 B2-class trams built between 1987 and 1994. All were built by Comeng and later ABB in Dandenong.[2][3] They were the first articulated trams on the Melbourne tram network, and the B2-class were the first air-conditioned trams.[6]

On the request of the Victorian transport minister, who wished the last of the B2-class order to be low-floor trams, an articulated low-floor design was developed by Comeng from 1989. The tram was to ostensibly utilise the components from the B-class and be partially low-floor, with internal stairs over the bogies. The design progressed quite far, with concept art, design schematics, and a mock up produced, and work on the first body shell commenced.

The project was cancelled in 1990, with the new transport minister opting to finish the full B2-class order instead of the low-floor variant; this was on the back of disputes between Comeng and the Public Transport Corporation, a cabinet reshuffle, and ABB's acquisition of Comeng.[7]

The prospect of low-floor access was raised again in the late 1990s when the Public Transport Corporation considered adding a low-floor section to the B-class trams, between the two sections. However, at a cost of $700,000 per tram it was not considered cost effective, and not carried out.[8]

When the Melbourne tram network was privatised in August 1999, 55 B2-class passed to M>Tram, while the two 'B1-class' and other 75 B2-class went to Yarra Trams.[9] All became part of the Yarra Trams fleet in April 2004 when the network was reunited.[10]

In 2007. the dot-matrix displays on the B1 class trams were replaced with LED equipment, and cab air-conditioning was fitted in 2009. In 2014, an upgrade of the interiors commenced. Seats were removed and replaced with 'lean seats' as fitted on the C and C2 class trams, that increases capacity by seven to nine passengers while providing space for prams and shopping carts, while extra hand rails were also be installed floor to ceiling, and seats will be re-covered.

These changes were aimed at increasing capacity while providing better use of space and flow through the vehicles. Step-well lighting was also improved, providing better visibility by changing to LED lighting. The program aimed to add capacity of approximately 1,100 passengers to the B-class fleet and was completed in early 2014.[11]

In June 2015, the installation of automated onboard passenger information system, similar to that used on the E class fleet, commenced at Camberwell depot.[12] This program also changed over the entire B class fleet destination displays from the previously fluorescent-lit dot-matrix to the more visible, bright orange LED type seen on the Z3 class.

Subclasses

B1-class

The B1-class comprises two trams built as prototype light rail vehicles built by Comeng in 1984 and 1985 for the St Kilda and Port Melbourne light rail conversion projects.[4] Both B1's were fitted with air compressors and air brakes[2] (the only other trams currently in service also fitted with air brakes are the W class), and were originally fitted with both trolley poles and pantographs. They were originally built with dual-height steps to allow for level boarding at railway platforms and street level, but both have had these features removed, with low floor stops build adjacent to the railway platforms instead. They have a very similar interior to the B2-class, except they have no air-conditioning, and are fitted with opening windows and different sun shades.[2]

B1 2001 was delivered to the Metropolitan Transit Authority on 7 February 1984 and entered service on 19 December 1984, while B1 2002 entered service on 17 December 1985.[13][14] Both initially operated out of Camberwell depot on routes 70 and 75, before 'B1 2001 was transferred to South Melbourne and B1 2002 to North Fitzroy in 1987 when the St Kilda and Port Melbourne lines opened.[15] Both had compressor issues in the early to mid 2000s, but were later rectified, both being based at East Preston depot by this stage.[2][14]

In 2016, both B1-Class trams were meant to have been withdrawn after an organised farewell tour was hosted by Yarra Trams on 2 February 2016.[16] However, as of August 2016, B1.2001 remained in service while B1.2002 was in storage.[2]

As of November 2017, both B1-Class trams were in long-term storage at Preston Workshops after its final run around Melbourne on the 12 November 2017. B1.2001 remained in operational state representing the B1-Class trams, but B1.2002 was taken apart for parts for B1.2001.

In February 2018, both B1-Class trams were withdrawn from Yarra Trams services.

In November 2023, B1.2001 was transferred from Preston Workshops by road to a scrapping facility. Meaning no examples of the B1-Class trams in operable state exist.

B2-class

Following the B1-class trams, an order of 130 B2-class trams was completed by Comeng (later ABB) between 1987 and 1994, originally for the St Kilda and Port Melbourne light rail conversions, they quickly spread across the system.[4] Although quite similar to the 'B1-class, they differed in several ways, they were the first Melbourne trams to feature air conditioning, include dot-matrix destination signs, and although the electronics of the B2-class were similar to earlier Z3 and A-class trams, they were fitted with GTO control systems.[4][3]

It was intended that they be used to replace trains on the Upfield railway line but this did not eventuate. In September 1992, the 100th articulated tram for Melbourne, B2 2102 was delivered in 'chocolate and cream' livery, approximating the M&MTB colours of the 1920s; it was also re-numbered as 2100.[15]

In February 1992, 2089 was taken to Canberra and displayed in the city as part of a promotion for a planned light rail scheme.[17] In November 2001, 2057 and 2059 collided on the corner of Nicholson Street and Victoria Parade. The undamaged portions were married together as 2059 while the two damaged portions were rebuilt at Preston Workshops and returned to service as 2057.[18]

In 2003, Yarra Trams refitted ten B2-class trams with the "Apollo" seating layout, in which some seats were replaced with "bum racks" (similar to those seen in the C-class trams), in an effort to increase passenger capacity.[19] All B2-class trams remain in service and are painted in either the Yarra Trams livery, or have all-over advertising applied.[3]
