I think the problem few people talk about is the small, in-city rail lines that used to exist that don't anymore. 100 years ago the city I live in had dedicated rail lines going to every major factory in the city - there was little need for last-mile trucking. AFAIK there are no western cities that are organized like this anymore, so the best you can do is deliver goods to a rail station and truck it from there - this requires a bunch of temporary storage space to transfer cargo and delays everything.
Here's another example - look at all the little rail branch lines servicing parts of 1944 Boston: https://ngmdb.usgs.gov/img4/ht_icons/overlay/MA/MA_Boston%20...
I don't know how you bring that back after decades of building for cars.
