But the 0-8-0 USRA switcher was ubiquitous. Every railroad owned them;
I bought my pair only because I wanted to turn them into P&LE "Bulldogs" They were a convenient disappointment as shortly thereafter I decided that P&LE switchers did not fit the concept of my pike. The only 0-0-8s that either B&O or WM had were those converted from 2-8-0s, so I had no use for the USRA 0-8-0. B&O did have USRA 0-6-0s.
FM is the only major builder whose yard goats we are missing; at least one that meets to-day's standards. I would buy FM yard goats. For diesels, I want to see those and Baldwin road switchers.
