School does not stop at 30 degrees below zero on the Hi-Line. Neither do the buses. The district’s shop foreman, Seth Hamilton, decided to put the electrics to the test. He didn’t expect the EVs to outperform his diesel Bluebirds, even on a day so cold it took a cocktail of additive and diesel to prevent the bus fuel from coagulating.

“Actually, if I was going to jump into one of our buses on a cold day, I’d take the electric,” Hamilton said, Thursday, now 11 months into the era of EV buses.
