problem was the overhead wires, rebuilt in April and June for the new trams. This was done in a hurry and of poor quality, causing the Ganz trams still running to have problems with their pantographs. On July 15 one traction mast fell to the road on the Margaret Bridge, causing tram services to be suspended between Jászai Mari tér and Moszkva tér till July 25. In the last week of August the overhead 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. Almada Metro Transportes Sul de Tejo (MST) ordered 24 four-module Combino Plus vehicles for a new light rail system in Almada, south of Lisbon. The first unit was delivered by the end of May 2005, but after the problems with the Combino surfaced the order was converted to stainless steel-bodied Combinos, to be delivered by 2007. Melbourne Siemens leased Almada tram C008 to Melbourne's tram network for research and development purposes. It entered service on Grand Prix shuttles on route 96 shuttles on 18 March 2007, before commencing a three-month stint on route 16 the following day, running alongside the classic Combino and other tram models. Toronto The Combino Plus was offered by Siemens in August 2007 in its bid to deliver 204 articulated, low-floor vehicles for the Toronto streetcar system as replacements for aging CLRVs and ALRVs. These three-module units were supposed to be in length, have a width of , and carry 183 passengers. Siemens withdrew their first bid, citing an inability to meet the TTC's 25-percent Canadian content requirement. When tenders were reopened in August 2008, Siemens bid again using the same model, but their price was 50 percent higher than that of Bombardier's locally built Flexity Outlook model, who subsequently won the bid. Siemens Avenio The Avenio brand was introduced at the UITP 2009 trade fair in Vienna, marketed as the "longest tram in the world" with 100% low floor (referring to the 72 meter version with eight modules). Avenio is based on the Siemens Combino Plus but is simplified. There is now one secondary spring which now
