First cars, now trucks: Biden takes aim at tailpipe pollution
wapo.st
The Environmental Protection Agency finalized rules Friday requiring reductions in tailpipe emissions from new trucks, delivery vans and buses.

Yet EPA officials said the rule will not mandate the adoption of a particular zero-emission technology. Rather, it will require manufacturers to reduce emissions by choosing from several cleaner technologies, including electric trucks, hybrid trucks and hydrogen fuel-cell vehicles.

    Considering locomotives are diesel-electric hybrids, it would make sense to move trucks to a similar technology. Replace the weight of a huge engine and transmission with a smaller generator and battery pack.

      I don’t believe locomotives have batteries - the generator output directly feeds the traction motors. The locomotive power curve is basically - a shitload of power near zero speed to get the train moving, or a shitload of power at cruising speed to keep it moving; not so much stop and start and various speeds like most road vehicles. So a battery energy reserve doesn’t do much.

      And locomotive engines are some huge, heavy mofos.
