“Thank you for visiting the 150HP Case homepage. LET’S KEEP HISTORY ALIVE.” -Kory Anderson, 150HP Case Engineer





overview
THE 150 HP CASE IS THE LARGEST STEAM TRACTION ENGINE EVER PRODUCED. Built originally in 1905, zero of them ever lived on – until recreated from scratch in 2018 by Kory Anderson.
The journey of the multi-year build was followed by more than 10,000 followers on Facebook and eventually led to more than 5 million views on YouTube with his legendary “engine pull” in September 2019 at the Western Minnesota Steam Threshers Reunion (WMSTR) in Rollag, Minnesota. This site is a place for steam engineers and hobbyists to learn more about bringing the 150 Case to life.
