An old favorite of mine was one by Tom T. Hall called "The Engineers don't wave from the trains anymore."I only saw it on one album that he did, a bilateral mutual appreciation disc with Earl Scruggs (I forget the title, but its a great album)
The engineers don't wave from the trains anymore,
Not like they did in 1954
They got computers and diesels and such
And the engineers don't wave from the trains anymore,
The engineers don't wave from the trains.
When I was a little boy I'd hang around the track
I'd watch them trains going to Louisville and back
I had my dreams, and I had my plans,
I was going to be a train driving man.
There's more, but memory fails at the moment.
