The Uetliberg line in Zurich is Europe’s highest grade standard gauge adhesion railway, going from 1,299ft to 2,667ft in 6.4mi. It maxes out at 7.9% as it reaches the top of a local mountain. (Lisbon has the steepest adhesion railway line — a tramway — at 13.8%.) #ZurichUrbanism

The Uetliberg line is optimized to have two services. A shuttle line from Zurich HB to Zurich Tremli on weekdays and a full line from Zurich HB to Uetliberg all days of the week. This leads to an interesting service pattern. #ZurichUrbanism

On weekdays, this arrangement ensures all stations from Zurich to Zurich Triemli get service every 10 minutes and all stations from Zurich Triemli to Uetliberg get service every 30 minutes. On weekends, all stations along the line get service every 20 minutes. #ZurichUrbanism

What’s so interesting about this all is that Swiss engineers designed the line with the service pattern in mind.
The Uetliberg line is mostly single track. Key sections of the line have an extra passing track for precise timed passes, optimizing investments. #ZurichUrbanism
Though rare in the US, the Swiss widely employ use of rack railways for intercity rail and short lines. Rack railways come in a variety forms to provide traction on steeper inclines (usually over 10% grade). Speeds on them differ by circumstance, but can be quick. #SwissUrbanism

Trains on rack railways have an extra “wheel” that grips the extra tooth rail inlaid in a trackbed. Rack rails can be intermittent being provided only when necessary on a rail corridor for traction and reverting to standard track otherwise, a common Swiss practice. #SwissUrbanism
