I can't believe that in this day and time we as a region are considering purchasing buses that run off of diesel fuel. Diesel fuel is foreign oil. So-called "clean diesel" is still diesel, and therefore is still foreign oil. Natural gas is an American resource.
The life-cycle for this proposed bus fleet is said to be twelve years. Who wants to still be running diesel buses in Dallas in the year 2020?
Throughout our nation, we have been beholden to foreign oil interests and when the price goes up we all feel the pain. Automakers and other industries are being forced to retool and become more fuel-efficient and environmentally responsible. Why wouldn't DART follow the lead of the City of Dallas as well as other area municipal transit organizations and buy CNG buses?
