Ride Smoothness Explained – Theme Park Definition

Smoothness (German enthusiasts call it "Laufruhe") describes how cleanly a coaster's trains track through the layout without head-banging, shuffling or vibration. It is shaped by the precision of the track manufacturing, the train and wheel design, and the ride's age and maintenance. Makers like B&M and Mack are renowned for glass-smooth rides, and a coaster keeping its smoothness as it ages is considered a mark of engineering quality. The opposite — a rough, rattling ride — is one of the most common enthusiast complaints.
