"The 505 new buses will include a 250/255 split of Euro 5 Volvo diesel buses and CNG Mercedes buses that will allow State Transit to make strategic decisions about the use of the rights buses in the right parts of their contract areas. The 250 Euro 5 diesel buses and 255 CNG buses are expected to start entering into service early in 2007. The Euro 5 diesel engine is the latest in environmental technology offering the greatest benefits both environmentally and operationally. Under current negotiations, NSW is likely to be one of the first jurisdiction in the world to begin running the brand new advanced Euro 5 diesel engine. The 505 new buses will be in addition to the 100 new standard buses and 80 articulated buses that are being delivered as part of 2004/05 contracts. The 2005/06 financial year saw the addition of 77 new buses to the State Transit fleet. These buses were made up of 22 B12LE Volvo buses (Volgren body), five B12LE Volvo buses (Custom Coach body) and 50 B12LEA Volvo articulated buses."
