This was the first time that the roller coaster track would be all with one rail.

This innovation was made to let the riders have a longer ride by switching track types during the ride.
The powered chainlift helped roller coasters go up steep hills, leading to a big drop, and extending ride time. It hooks onto the train, and a motor pulls the chainlift and train up.

Side Friction Coaster
Leaps and Dips Park
The Side Friction Coaster existed before underfriction became a realistic addition to a roller coaster. Side friction coasters had plates on the sides of the wheels to keep the cars from derailing. A brakeman had to ride on these coasters because they would derail if they went too fast
The first lapbar helped keep riders in place during a steep bank. It was very unpopular, and took a long time to catch on.

Underfriction Roller Coaster
Underfriction wheels are above and below the track, keeping the coaster on the tract during intense movement.

Magnets and Electrical currents harness electrical currents within the coaster, which propels it.
First Full Speed Uphill Launch
Bolliger & Moillard
It uses a set of large generators to propel the roller coaster uphill from 0-40 mph in 2.0 seconds.

Magnet brakes vary the flow of current in a small magnetic field, which increases durability and cost effectiveness. Most modern coasters have this mechanism.
Eight huge hydraulic pumps sit under the launch area, and pressurize the hydraulic fluid, sending the roller coaster out at a very high speed. The fastest roller coasters in the world have hydraulic catapults.
