Actually....I'm so interested in this now that I've been searching the Web for more info. Here's what I found out about the NYC FA.
That unit is reportedly owed by the Anthracite Historical Society. The NYC paint job was temporary, added for a showing, but not its original. Therefore, I question if the 1994 photo I listed the link to was the same loco. But this one (the one I took), is supposedly being restored to Lehigh Valley #596. Prior to that is was Long Island #604 and L&N #315. The unit supposedly has a working 244 engine.
I found this info by doing a search for "Southern Railroad of New Jersey" -- the current owners of the junction I took the photos at.
