One of the few remaining structures in the East Broad Top RR's Mt. Union yard is the Engine House.
The Engine House has two stalls; the left stall can accomodate either a standard-gauge or a narrow-gauge engine. The left stall has four rails - standard-gauge and narrow gauge
centered on the standard-gauge rails. A single-point switch just outside the Engine House is used to traverse the narrow-gauge engine from the common SG-NG rail to the separate NG rail.
Although three rails lead up to the right stall, it can only accomodate a standard-gauge engine, as the narrow-gauge rail stops just inside the door at the edge of the inspection pit. I presume the inspection pit was
added after the Engine House and associated trackage were originally constructed.
The right-side stall contains the EBT's standard-gauge 0-6-0 switch engine #3, stored in inoperative condition. The left-side stall contains the Mt. Union Connecting Railroad's standard-gauge #1 Plymouth CR-4 diesel-hydraulic switch engine.
In recent years the engine house was in deterioriating condition, but after recent roof repairs and repainting, it looks good for a number of years to come.
