There is one red and one blue train on each side for a total of two trains on each side. When only running one train on each side, an effort is made to run a train of each color. There are often fun spirited arguments on the lift hill about which train is better.
Rebel Yell originally ran parallel to Lake Charles, a large man-made lake on the northwest corner of Kings Dominion. Two thirds of the lake was drained in the early 1990s when the space was needed for construction of a water park. (The Anaconda roller coaster still runs over and under the remainder of the lake.) The roller coaster now divides the water park in half with a walkway running under it.
The trains on one side of Rebel Yell were turned to face backward from 1993 until 2007. Beginning in 2008, both trains were faced forward again so that the ride operates under the train manufacturer's specifications.
