Status of K-4 rebuilding at Steamtown?

I just read an article in an antique car magazine about a car show at Scranton this summer. The author said he was driving down the main street when he spied a Pennsy K-4 steaming across an overpass up ahead. He seemed to know what he was talking about, so I doubt it was one of Steamtown's Canadian engines.

Has the K-4 reached the stage of being test-fired? If so, I've not read about it anyplace else.

Anyone know anything about this?

Thanks!

i heard she was at EBT idk where the tendor is. they ruined her boiler from firing her up yrs ago. didnt let he warm up before moving her.
