The D1 class, or Combino (affectionately known as "Bambino"), electric tram operates in Melbourne, Victoria, Australia. It was built by Siemens, and the first unit was delivered to the city in 2002. The trams were initially operated by M>Tram, but are now operated by Yarra Trams.
The D1 class is a 3-section tram and can be found on Melbourne's southeastern and inner tram routes. They are all based at Malvern tram depot. The trams feature plug-type doors, next-stop display, and several other features. The trams are built '100% low-floor.'
Tram D1.3507 has been shipped to Siemens in Germany being rebuilt, due to arrive back in Melbourne in 2005. All D1 class trams have now being restickered in Yarra Trams livery.
All D1 Class Trams have an traction braking controller with an intergral deadman's trigger the driver MUST release and reapply every 1 minute, if an alarm sounds they must release and reapply immediately, otherwise magnetic track brakes are applied at full force.
Originally driver could hold it down conintuoulsy while the tram was moving, if driver took their hand off, an alarm would sound, followed soon by track brake application. If after four mintutes it had been held-down continuously and the tram stopped, the driver would get an audible warning and the tram would not move until the driver had released it. There was also an alternative deadman's button on the side of the armrest. Drivers discovered that if the armrest were dropped low enough, this button would stay pressed without the driver appying any pressure, they still had to be released every four minutes when coming to a stop. But as soon as the manegement discoverd this, their reaction was vigilance control, actually a deadman's vigilance device, and hence the notice in the cab "Vigilance control now fitted, release and reapply every 1 minute, if an alarm sounds, release and reapply immediately."
