So what is a hybrid style roller coaster and how do they differ from what is typically called a steel or wooden roller coaster. A hybrid is a type of coaster that utilizes either a steel support structure with a wooden type track system. Or a wooden support structure with a steel type track system. Example of a steel track, it has a steel running tube used as the rail with a steel structure holding them together. There are lots of different designs from B&M track to Intiman track and various other types of track. I also consider RMC Rocky Mountain Construction IBeam track as a steel track system. The track is a solid steel piece of track held together by steel connectors. It just looks different than traditional round tube track but its purpose is still the same IBEAM track just happens to be square shaped.
