Church was working on side-friction roller coaster car designs and began developing an interest in inventing new rides.
The most famous roller coaster in the world today, the Cyclone at Coney Island, is similar in design to the Big Dipper.

Prior and Church coaster trains typically consisted of ten or eleven single-bench cars with open-air fronts, each bench securing up to three riders with a leather strap lap restraint.
