<P> Unlike most racing coasters, Rolling Thunder's tracks were not always next to each other, they separated at several points in the ride . After the first drop, the left track traveled over a big hill, followed by a small hill, whereas the second track reversed that . On the turnaround at the back, the left track traveled up and made a level turn, while the right track traveled up and dropped while turning . The hills on the return segment were also staggered . The trains were not always raced . </P> <P> There were four trains that were distinguishable by color: Red, Blue, Yellow and Green . Each train had four three - bench Philadelphia Toboggan Coasters cars held together by hitch bars . Each car contained six seats . Each train held a maximum of 24 riders . </P> <P> The trains used buzz bars that locked in one position . Seat dividers and headrests were added in 1981 to prevent people from standing on the ride while it was in operation . Seat belts were added on the ride's 30th anniversary . </P> <P> There were three types of wheels used on the trains . Sixteen road wheels rode on the steel layer on top of the track . Sixteen guide wheels guided the trains around the turned on a separate steel track located on the sides of the wooden track . Sixteen upstop wheels rode on the bottom of the track . </P>
