The railroad that most likely would have been the "other" connection to the EBT was the Ma & Pa. It started as a narrow gauge line and it proosed at one time to build west to connect to the EBT and then east to Philadelphia. Obviously neither proposal was acted on, in part because there was no good way to cross the mountains other than the route used by the B&O and WM through Cumberland.

EBT interchanged with the PRR at Mount Union, PA - its only connection to the outside world. South of Mount Union, it climbed up into the coal fields on Broad Top Mountain. It was several dozen miles (and a mountain range) away from the closest B&O trackage.
The EBT still exists. Most of it hasn't been operated since 1956, but the rails were never taken up.
