The Combino Supra Combino MkII, or Combino Plus is a new Combino
Combino
The Combino is a low floor tram produced by Siemens Transportation Systems . The first prototype was produced in 1996 at the Duewag works in Düsseldorf; the trams are currently made in Krefeld-Uerdingen. Because of its modular design using standardised components, and the resulting reduced costs,...

Design differences with original Combino


Unlike the former Combino model, the Combino Supra is designed in nine meter fixed sections. Each section has a bogie

, either powered or unpowered. The tram length can be anywhere from two sections (18 meters) to eight (72 meters). In the Budapest and Almada trams, modules are placed in two car blocks, each block joined by a double articulation join. This is in contrast to the original Combino, and other articulated low floor trams, where modules are suspended between others. Siemens claims the axle load

 of this design is 10 metric tonnes for a tram width of 2.65 meters, such as the Almada tram.

For the Budapest order, the tram went from nine modules of the original Combino to six modules for the Combino Supra.

The original Combino design featured a half-width door near the drivers cab. The Combino Supra has changed this to a full double-leaf door.

In the summer of 2006 problems arose with the Budapest version of the Combino. On August 1, 2006 Budapest mayor Gábor Demszky

 ordered all six Combino trams to be withdrawn from service until technical problems that arose in the previous months were cleared up. There were problems with the doors, caused by sensitive fail-safe systems which brought trams to a halt for reasons including luggage or the odd leg getting stuck in a door. Siemens AG reportedly admitted the door problem to be a "design fault".

Another problem was the overhead wire system of the track, which was rebuilt in April and June to accommodate the new trams. The rebuilding was done in a hurry and of poor quality, causing the old Ganz trams still running on the track to have problems with their pantographs

, causing tram services to be suspended between Jászai Mari tér and Moszkva tér till July 25. In the last week of August the wire system was adjusted to prevent new problems from occurring.

The teething problems were eventually sorted out, and all 40 trams were in regular service by the summer of 2007. But Siemens realises further improvements in the ventilation (the vehicles were ordered without air conditioning), and door closing signals will be changed, after inhabitants of the streets passed complained that they are too loud by night.
