Along with the layout of the coaster this serves as a nice snapshot at the park at the time. Click the larger version to see all the other rides named on there - Miniature Golf, the Spectacular, Iceberg, Penny Arcade, Merry-Go-Round, Journey to the Center of the Earth, and more are listed. Several other rides are in locations that that have since changed.
The layout of Hercules is placed over the park as it was at the time, you can see that the station area for the coaster sat pretty directly over one of the racetrack's turns. The coaster may not have stood the test of time, but it's hard to argue that it didn't help propel Dorney Park to a 'next level' in its development.
