Boomslang

Boomslang is an Inverted Impulse Coaster themed after the venomous African tree snake of the same name. The train's color scheme is that of the snake itself, the track and supports are the tree. It's the tallest and fastest inverted impulse coaster yet built, reaching a speed of 80 MPH and a height of 270 ft. It has a nine-car train, a twisted front spike and a straight back spike with a holding brake. It reaches a maximum G-force of 4.7, in the front seat after the second forward launch. Its capacity (assuming 50 seconds of load/unload time) is 1178 riders per hour.

If the holding brake doesn't work, just open it in the editor, open the brake's settings and slide the "position on section" slider SLIGHTLY towards End. It's designed to hold the train in place precisely at the point where it naturally stops moving upward, if the train is going slightly too slow it won't reach the trigger point and the brake won't activate.
