You may recall that I really like the train pics that Maya posts here.
Well, I like trains.
Ran across this rather lengthy, but detailed article about possible reasons for the “supply disruptions” going on.
The writer describes the troubles that have come with running 16,000 foot long trains.
He goes into the construction and running of these multi-mile long trains.
Amazing, and to me, a very disturbing story.
