The Voralpen-Express (VAE) is a named train connecting small to medium-sized cities and villages in Central and Eastern Switzerland on a scenic route, carrying this name since 1992. It is operated by Südostbahn (SOB) and runs every hour as an InterRegio (IR) between St. Gallen and Lucerne, bypassing Zurich. Its name derives from the fact that it traverses the Prealps (German: Voralpen).
