Because of #5049's accident the other day, is it possible that they could very well remove those buses and buy more Nabis?
NY Did it....Bmore was doing it, but they still running them as best as they can, I wouldnt be suprised if ART did. Those buses have a crappy little "engine" back there.
I'm not sure about ART's CNGs, but I know that the MTA's #1300s did not feature an engine. If I remember correctly, they had a Capstone C30, and then later a C65 turbine system.
