Myersdale Trailhead

There are a number of great places to stop along the Great Allegheny Passage trailand the Myersdale Station is one of them.

When the Western Maryland Railway was being constructed in 1910, the railroad’s real estate agent promised he would build “the finest station between Cumberland and Connellsville” if the town fathers would grant permission to build the railroad through Meyersdale

Permission was given, and the brick semi-Tudor style station was the result. Initially, the depot served two passenger trains in each direction daily, but regular passenger service ceased in 1931. The station continued to serve freight customers and as a maintenance base. After the Western Maryland Railway was abandoned in 1975, the building fell into disrepair. The station is owned by the County of Somerset. The Historical Society leases the station from the owner. The station has been restored to its 1911 external appearance and was reopened to the public in 1995.

Salisbury Viaduct

At a little more than 1/3 mile the Salisbury Viaduct, (1908 feet long) dominates the Casselman River Vally. The 101' high steel trestle was a key engineering achievement fro the Western Maryland Railway's Connersville Extension. Abandoned as a through-route in 1975, it was decked for trail use in 1998.

Eastern Continental Divide

Generally eading from West to East or more accurately 123 degrees NW-SE

The Eastern Continental Divide (ECD) is the highest point on the Great Allegheny Passage (GAP) at 2,392 feet above sea level, Water on one side flows to the Chesapeake and the Atlantic Ocean, on the other side, it flows to the Mississippi and the Gulf of Mexico.

More importantly to me it means the long but shallow incline from Pittsburgh, becomes all downhill to Cumberland.
