700 Propane Vehicles And Still ‘Moving Aggressively’ To Alt. Fuels
Student Transportation Inc. (STI), one of the largest school bus transportation services companies in North America, highlighted its work with alternative fuels in a recent update for investors.
Last week, STI said that about 700 new propane autogas buses came online in its fleet during fiscal-year 2013, which ended on June 30. The company now has almost 1,000 vehicles that run on either autogas or compressed natural gas (CNG), as well as another 1,800 that are compatible with biofuels.
