"questionable" longest fact I found:
The Longest Train in The World
The train from Nouadhibou to Zouerat in Mauritania is the longest train in the world. The iron ore train carry thousands of tons of crushed rock in a chain of wagons up to three kilometres long.
3km = 1.86 miles....I say questionable but I mean b.s. since I was landing in Omaha NE to visit the Union Pacific RR for business, and the train I saw heading out of the Powder River Basin coal fields was many more miles long than a mere 1.86.
