It was designed to be the best locomotive that Baldwin ever made. It boasts three cylinders, weighed about 350 short tons (318 t; 313 long tons), including tender, and can pull a load of up to 7,000 short tons (6,400 t; 6,200 long tons). Its top speed is 70 mph (110 km/h).
60000 was very innovative, carrying unusual technology, including a water-tube firebox. This was intended to improve efficiency but the tubes tended to burst inside the firebox. It is also a compound, expanding the steam once in the inside cylinder and then again in the two outside cylinders. Although compounding increased efficiency, it was an extra complication that the US railroads had mostly rejected by the middle twenties. Also, the weight and length of the engine was too much for all but the heaviest and straightest track.
This locomotive was experimental and was meant to be the model for future development. However, its demonstration runs never persuaded railroads to purchase more and in 1933, it was purchased by the Franklin Institute Science Museum for $1 and remains there today.
