Arizona Transit Agency Introduces New CNG Buses

On Thursday, the City of Tucson and Sun Tran (the transit agency that services the Tucson area) introduced the first of 24 new Gillig low-floor CNG buses. The new buses, which replace 14- year old natural gas buses, will be fully received by January 2015. The new buses feature technological improvements, including a more efficient engine and an EMP cooling system with eight electric fans that improve the fuel efficiency of the vehicles and reduce overall emissions. The CNG buses were purchased with funding from the Federal Transportation Administration.
