> we all know already they are big polluters but we kinda have to deal with it. There is a lot of variation in train emissions, but most modern ones (electrified) have minimal emissions - and far lower than electric cars even, per passenger mile or per tonnage transported. Even the oldest ones in common use (diesel electric) are more efficient per ton-mile and passenger mile than a typical car.
