As long as Mean Streak has trains on it that can't go around flat curves, there are only two ways to eliminate the shuffling:
A) Eliminate the flat curves by insuring that all curves are banked. Mean Streak's train handles banked curves just fine, so long as the
lateral alignment through the curve is a straight line.
OR...
B) Install a train which is capable of handling flat curves. See Hersheypark's
Lightning Racer, Seabreeze's
Jack Rabbit, PNE Playland's
Coaster, Cedar Point's
Cedar Creek Mine Ride, Gemini, Magnum XL-200, Corkscrew, Raptor, Mantis:TCFKAB, Millennium Force, and
Woodstock Express for examples of how it might be done.
