In the East Broad Top section are photos of the Mount Union Enginehouse, with a slope-tender 0-6-0 inside.

Is this from the standard-gauge side of the EBT?

Does that engine/enginehouse still exist, and what is the engine's heritage?

EBT # 3 was built by Baldwin in 1923 for the East Broad Top. It is now listed as unserviceable but remains in the enginehouse. It was used for switching in the standard and dual gauge sections of the Mount Union yard. Chris Coleman's site at http://spikesys.com/EBT/ contains a wealth of information.
