I would assume it means the slow train that stops at every stop and sometimes in between. Maybe even to a hand wave. I've heard the term for years but never thought about it.
When in the Navy at Key West, we used the term frequently. Each Naval Air Station on the East of the Mississippi (and I assume west also for their stops) took turns at what we called the 'milk run'. When it was our turn, we would fly up and down the East Coast carrying anything (that would fit) or anybody that the Navy or Marine Corps (or any other service, I guess) needed carrying. We'd carry spare parts, aircraft engines, sometimes entire units being transferred or a detachment being moved from their base to where a ships port was. Often enroute we would get a radio call, go here pick up this, etc etc. That was the milk run. I imagine the Lindberg train was similar.
