The Steam Engine on the Swiss Steam Ship Stadt Zürich, built in 1909 by Escher-Wyss in Zürich. It has 370 kW (500 HP) at 57 RPM. The other Lake Zürich Paddle Steamer Stadt Rapperswil has an almost identical Engine, as well as the Paddle Steamers Lötschberg and Hohentwiel on Lake Brienz and Lake Constance. Special Thanks to @zsgch for allowing me to make this Video; usually Passengers can't visit the Engine Room.

Der andere Zürichsee-Raddampfer Stadt Rapperswil hat eine nahezu identische Maschine, ebenso die Dampfschiffe Lötschberg und Hohentwiel auf dem Brienzersee bzw. Bodensee, sowie noch ein paar weitere Schiffe.

Typo Correction: 10 bar equals 145 PSI. No Idea how the 0 got there.
Additional Information on Compound Engines:
When Steam expands in a Steam Engine, it cools down. The Cylinder Temperature is somewhere between the fresh Steam and exhaust Steam Temperature, usually about the middle. This causes Steam to condense on the Cylinder Walls when it enters the Cylinder. By having separate high and low Pressure Cylinders, you decrease the Temperature Reduction in each Cylinder and thus the Temperature Difference between fresh Steam and Cylinder Walls, thus reducing Condensation. Another Advantage is the Possibilty to reheat the Steam between the Cylinders, but that is rarely done in Piston Steam Engines and more of a Turbine Thing.
