Data from "Pittsburgh Four-Wheel Saddle Tank Engine", Railway & Locomotive Engineering, Vol XIII, No. 1 (January 1900), p. 8. Probably works number 1700 in March 1897, 1701 in April, and 1777-1778 in January 1898.
The saddle-tank on this diminuitive industrial switcher had a flat top that was exactly even with the top of the cab and the stack. Rumary's list of Pittsburgh locomotives identifies these as 0-4-0s (implying a tender), but the number on the cab in the R & LE illustration is 4, suggesting that it was this saddle-tank design that was delivered.
