The 150 HP Case is the largest steam traction engine ever produced, originally built in 1905 as a powerful symbol of early American engineering. However, none of the original models survived over time. In 2018, steam enthusiast and engineer Kory Anderson brought history back to life by recreating the massive engine entirely from scratch, using original blueprints and traditional methods. His work revived a lost piece of industrial heritage, making it the only operational 150 HP Case in existence
