Re: Don't forget truck drivers
"much more so than in the UK/EU where rail is used much more extensively so there is much less long haul trucking."
Whilst I agree with your post, I'm not sure the above is true. I don't see freight trains with random containers on the flatbeds. What I tend to see are freight trains made up of one long train with identical tank or coal-like wagons in the make up. I spend most of my day on the road, and lorries make up a large part of the traffic on the roads here in the UK, many still EU registered trucks. Rail freight may possibly be a larger percentage than in the US, I don't know, but it doesn't seem to be a significant percentage based purely on my observations and "feeling".
We used to have a fairly decent number of "Freitliner" terminals around the country where local trucks would deliver standard shipping containers, forward them by rail, and get picked up by truck at the other end for onward local delivery. Many no longer exist, the remaining ones seem to be just trucking hubs or container storage sites now with rare or no rail head any more.
