There is a max length and tonnage rule for van trains, but not for freight. The vans can't exceed 10,000 feet or 9,000 tons and that rule is followed to the letter.
Freights are more go with what is known to work. The 70 ACe's and MAC's are known to pull well so they will go with two of them on an 8,500 ton train. The GE 6,000 HP engines will pull to, and faster as long as the rail is dry. They are slippery when the rail is wet.
