Breakdown

A Ride Breakdown occurs with most rides in RollerCoaster Tycoon, RollerCoaster Tycoon 2 and RollerCoaster Tycoon 3. Breakdowns have a number of causes and a number of effects depending on the ride type and other factors. Breakdowns generally increase in frequency as the ride ages and as the reliability of the ride decreases. Adjusting the inspection time for Mechanics can help delay this. Certain rides never break down, thus, never requiring inspection. A complete list of rides that never break down can be found here.

Safety Cut-out
This is the most common breakdown, and affects most rides. The details of the breakdown are not explained, but it has a number of effects. If the ride consists of trains or cars that are powered by the track, such as a Monorail or Car Ride, those vehicles will stop moving. If the ride is a roller coaster that consists of a lift hill, trains being pulled up the lift will stop once a breakdown occurs. In all cases, trains waiting to exit the station will not be allowed to depart until the breakdown is addressed, even if they have exceeded their maximum wait time. This is known as an emergency stop in RCT3.

Restraints Stuck Open/Closed
This breakdown occurs when the safety restraints on a ride either are stuck open after a train has loaded and is preparing to leave the station, or if the restraints are stuck closed as a train arrives in the station.

(Station) Brakes Failure
This is an often severe breakdown, where the brakes on a ride, specifically the brakes in the station, fail to function. This breakdown can often result in a ride crash if a train enters into a station at too high a speed while another train is waiting to depart, though whether a ride will crash depends on a number of factors including the size and speed of the train. This breakdown also affects brakes outside of a station, but does not negatively impact block brakes.

Vehicle Malfunction
This breakdown involves a problem with a ride train. It has no specific effects.

Control Failure
This breakdown affects the Merry-Go-Round, causing it to spin rapidly and for the music playing to speed up. The ride may begin to shake after it has broken down for a long period, but other than that, the control failure is pretty harmless and will only cause the guests to think, "I want to get off of *ride*." However, it can and does effect much more rides in RCT3 since almost every ride has a visible control panel.
