If Strasburg gets RDG#1187/SRR#4 running, she'll be a Pennsylvania built and operated loco running inside the state.

Actually, I'll plead guilty to misreading your question:

Somehow I read your question to involve steam BUILT IN Pennsylvania. I very quickly--being a trained lateral thinker--came up with Knox & Kane's loco, but then said, "No, built in Pennsylvania....."

Furthermore, the "traditional" definition of "revenue service" in the context of rail preservation involves non-excursion service. Thus, industrial switcher, yes; excursion steamer ordered by a railroad for excursion service but occasionally used on freight if the diesels break down, no.

Still serviceable? In theory, if you inspected the 0-6-0F and lubed the bearings and valve gear. Just pull up a 600-psi steam/water source next to it........ Though I'd definitely worry about the track at the current location........

OK If narrow gauge is part of the deal, are not some of the engines at the Cedar Point Park in Ohio products of the H.K. Porter plant is Pittsburg, Pennsylvania?

Lucky thing that Baldwin Locomotive was in the commonwealth!

That tends to make a lot more possible locos!

Well, heck -- what about park engines? The two Hershey Park Crowns are still alive and well, running for their original owner in exactly the service they were built for.
