Built by the Rhode Island Locomotive Works, this 2-6-0 Mogul type freight locomotive was retained two years after the Wabash had become dieselized because of a bridge which would not support the weight of diesel-electric locomotives. Number 573 weighs 215,825 lbs. in working order, has 64" drive wheels and 19" by 28" cylinders. It was one of the smallest engines operated by the Wabash. Number 573 was donated in 1955 by the Wabash Railroad. It is believed that this is the last remaining Wabash Steam Engine.
