AZ: Sun Tran Gets New Compressed Natural Gas Buses

June 26--Sun Tran will start running new, compressed natural gas buses by the end of this summer.

The agency has received the first of 24 buses that are expected to help improve air quality in the region and meet the City of Tucson's livability goals.

The first batch of buses are expected to hit the streets by the end of August, with an additional five buses scheduled to arrive in December, according to a Sun Tran news release.

Most of the new buses cost $512,000 each, with the most recent vehicle, purchased in fiscal year 2013, costing $610,000 for hybrid technology.

The buses will replace a group of 14-year old compressed natural gas buses in Sun Tran's fleet, decreasing the average age of the fleet from almost six years old to five.

The buses use a newer compressed natural gas engine, which produces lower emissions than standard fueled vehicles and older compressed natural gas buses, according to Sun Tran.

All of the replacement buses are low-floor vehicles, offering ramps and kneeling features to accommodate passengers with disabilities, as well as on-board cameras.
