Years ago. Google Earth historical imagery shows it in the same location and orientation in 1994.
Found on-line pictures showing the original orientation and the building was at some time moved closer to the track and rotated about 180 degrees (originally it was not parallel with the track.
See this photo found on Pinterest.
Of course, the building was moved to Ghost Town in 1952.
