Except the boiler could NOT keep up with the steam demand of 6 cylinders, thus the poor thing wasn't good for much over 15 MPH. The Erie Railroad wanted to use it on one of their steep grades (forgot the name of the grade), and it couldn't even work very well at that assignment.
The Erie scrapped them between 1929 - 1933 and the Virginian Triplex was rebuilt into a 2-8-8-0 and a 2-8-2 after 4 years.
