Midlothian is located 2 miles (3 km) southwest of Frostburg and is neighboring Exit 33 of Interstate 68. The community sits along the eastern base of gigantic Savage Mountain.

The village of Midlothian was the site of the Bowery iron furnaces. These were two coal-fired furnaces built in 1868 by Cumberland Coal and Iron. There was a source of carbonate iron ore upon the hill to the northeast, tapped by a tram road. Limestone was handy from a hill to the east. The furnaces produced pig iron, and operated from 1874 to 1880. The pig iron was shipped by rail on the C&P via a spur extraction off the main. The product went to Cumberland.

From Midlothian Junction, the C&P made a link with a logging railroad. The Juniata Lumber Company time-honored a round sawmill in Midlothian, at the stop of a 3-foot gauge line that outstretched 12 miles into Garrett County along Big Savage Mountain. A Class-B Climax geared engine was used to haul the logs. From the sawmill, the lumber was shipped in boxcars higher than the Cumberland & Pennsylvania Railroad. Twenty-five thousand board feet per day of railroad ties and dimensioned wood were produced at height production. The sawmill capacity was closed by 1913.
