Yes, the Mack railbus is at the Railroad Museum of Pennsylvania. It is currently stored under cover in the pole barn at the back of the property, but shortly it will be moved outside for a while as a concrete floor is added to the pole barn. Someday it would be nice to cosmetically restore the railbus to its original colors and lettering. There will be a lot going on around the railroad museum this spring as preparation for the long-awaited roundhouse are undertaken. This will include a lot of moving equipment around to be clear of the construction site.
