> This is kind of absurd, I have been on busses all over the country, a metro bus, is a metro bus. There are not really differences based on topography or climate. It definitely depends. The traditional yellow school buses here (Canada) use diesel, so they need things like glow plugs [0] and block heaters [1] to be able to run in the winter. But even that only helps so much, so when the nighttime lows are below –40°C, they cancel the busses since they know that they won't run. Most of the city busses here use natural gas, and they're considerably more reliable in the cold weather but if they're parked for too long on a really cold day (even while running), the brakes will freeze up and they won't be able to move [2]. Similarly, the busses need a fairly powerful heating system, since it's tricky to heat a large space when it's really cold and the front door is open half the time. But conversely, most of the busses have no A/C. Adding glow plugs, and block heaters, and brake dryers shouldn't cost hundreds of thousands of dollars, but a more reliable natural gas bus might be double the price of an unreliable diesel one.
