According to a 1952 Billboard magazine, Dorney added a new Ben Schiff kiddie coaster that year. This entry is based on that mention. Dorney is also known to have had a oval kiddie coaster called "Mini Coaster" from 1957 to the 1980s. Pictures of this roller coaster show wheel assemblies only believed to have been used by Carl Miler. It is thought these were two different roller coasters.
