Springfield Mass Transit is going green.
SMTD manager, Steve Schufel, says 34 diesel buses will be retired over the next year or so and replaced with 34 diesel-electric hybrid buses. He says the buses still run on diesel fuel but they will be able to shutoff at certain times and idle on electric power.
SMTD has also been using 22 compressed natural gas buses. Those first went into operation in 1996.
