<P> Several height classifications have been used by parks and manufacturers in marketing their roller coasters , as well as enthusiasts within the industry . One classification , the kiddie coaster , is a roller coaster specifically designed for younger riders . Following World War II , parks began pushing for more of them to be built in contrast to the height and age restrictions of standard designs at the time . Companies like Philadelphia Toboggan Company ( PTC ) developed scaled - down versions of their larger models to accommodate the demand . These typically featured lift hills smaller than 25 feet ( 7.6 m ) , and still do today . The rise of kiddie coasters soon led to the development of `` junior '' models that had lift hills up to 45 feet ( 14 m ) . A notable example of a junior coaster is the Sea Dragon -- the oldest operating roller coaster from PTC 's legendary designer John Allen -- which opened at Wyandot Lake in 1956 near Powell , Ohio . </P>
