Eli5 why are diesel/electric powertrains economical for trains but not used in large trucks?

Always wondered why it doesn’t make sense to use diesel/electric in large trucks. Assumed it’s because cost/complexity doesn’t out weight benefits, but not sure why. Thanks.

Highways have a maximum weight allowance. The heavier the truck is, the less cargo it’s allowed to carry. Electric motors in a semi truck would weigh thousands of pounds. The drawbacks quite literally outweigh any benefit.
