Colossus - a massive dual-tracked wooden coaster built by International Amusement Devices, debuted in 1978.  At the time of opening, the ride was the world's longest, tallest, and fastest roller coaster, and was advertised as the “greatest coaster of all time”.

Colossus' layout spans 4,325-feet in length; the ride features  a height of 125-feetand speeds up to 62 MPH.  Colossus utilizes a double out and back layout filled with several drops and turns.

When the the ride first opened, it had incredibly high negative and lateral Gs.   Because of this, the ride was reprofiled at the end of its first season.  More than twelve of the ride’s hills/dips were redesigned and forces were greatly reduced.

Also, the trains from Internationally Amusement Devices were replaced with ones from the Philadelphian Toboggan Company. In 1987, these trains were replaced with ones from Morgan Manufacturing.

In 1991, the popular “Double-Dip” element was made flat so that it could be used as a block brake; although this increased capacity, it further reduced the amount of airtime offered on the ride.

In 1984, the park tried something new... during the Halloween Event, they ran one of the sides with backwards trains.  This was extremely popular among guests.  Currently, Colossus runs backwards every year during Fright Fest and occasionally during Spring Break.

Although Colossus is not what it used to be before the modifications, it is still a fun wooden coaster and a significant ride in history.
