The Coal Hill Coal Railroad began as a coal mine on the north face of Mt. Washington, then known as "Coal Hill", begun by Jacob Beltzhoover in 1825.
 This mine was operated by a series of persons, finally by James M. Bailey, who extended the mine completely though the hill to the south side of the hill in 1861.
 The mine was then sold to the Pittsburgh Coal Company, and rails from the mine were extended an additional one half mile to a new coal mine on the south side of Saw Mill Run.
 The rails were extended to a third mine, for a total length of one and one half miles.
 In spite of this short length, the railroad had 3 locomotives and 280 coal cars.
 The narrow gauge railroad delivered coal from these mines to South Pittsburgh via an inclined plane, which ran from the northern end of the mine to Carson Street in Pittsburgh, Pennsylvania.
 The railroad was sold by the Pittsburgh Coal Company to the Pittsburgh and Castle Shannon Railroad in 1871.
 After this sale, the mine was enlarged to form the Pittsburgh and Castle Shannon Tunnel, and the train tracks were extended to Castle Shannon, Pennsylvania. Robertsdale, Pennsylvania
Robertsdale is an unincorporated community in Wood Township in southern Huntingdon County, Pennsylvania, United States.
 It is situated on Broad Top Mountain near the eastern slope.
 It was founded in 1872 as part of the construction of the East Broad Top Railroad and Coal Company as the original terminus and mining location.
 The town was created by the EBT's parent company, the Rockhill Iron and Coal Company, which operated most of the mines on the east side of the Broad Top Coal field.
 The initial focus of mining was the Houk Mine (renamed Rockhill Iron and Coal Mine #1) which predated the town, though as a much smaller producer.
 Later RI&C #5 became a large producer.
 Mines #2, #3 and #4 were in Robertsdale but were not large producers and operated only briefly.
 Later the EBT was extended to Woodvale, Alvan and new Alvan as the focus of mining moved along the coal seams, though Robertsdale remained the mining headquarters.
 Robertsdale was a typical coal ming town complete with company owned miner houses, a company store, a company owned water and power system and other company owned facilities.
 Coal mining and its support industries were the principal employers. McAdams, Pennsylvania
McAdams (also known as Montour No. 9) is an unincorporated community in Robinson Township, Washington County, Pennsylvania, United States.
 McAdams is located at the intersection of Pennsylvania Route 980 and North Branch Road 2.2 mi west-northwest of McDonald.
 The community is a coal town which was the site of the Pittsburgh Coal Company's Montour No. 9 mine, which closed in 1954.
 The Montour Trail passes through the community, as did a branch of the Montour Railroad during the mine's operation. Pittsburgh coal seam
The Pittsburgh Coal Seam is the thickest and most extensive coal bed in the Appalachian Basin; hence, it is the most economically important coal bed in the eastern United States.
 The Upper Pennsylvanian Pittsburgh coal bed of the Monongahela Group is extensive and continuous, extending over 11,000 mi through 53 counties.
 It extends from Allegany County, Maryland to Belmont County, Ohio and from Allegheny County, Pennsylvania southwest to Putnam County, West Virginia. Pittsburgh Coalfield
The Pittsburgh Coalfield (Pittsburgh Coal Region) is the largest of the Western Pennsylvania coalfields.
 It includes all or part of Allegheny, Fayette, Greene, Washington, and Westmoreland Counties in Pennsylvania.
 Coal has been mined in Pittsburgh since the 18th century.
 U.S. Steel and Bethlehem Steel owned Karen, Maple Creek, and Ellsworth mines.
 It is not possible to define sharp geographical boundaries for this district for none such exist or are reported differently.
 The largest company in this field was the Pittsburgh Coal Company, which later became CONSOL Energy.
 It is bordered on the west by the state of West Virginia, on the south by Panhandle Coalfield and Klondike Coalfield, on the East by Irwin Gas Coalfield, on the North by the Freeport Coalfield and at least one other coalfield.
 The Darr Mine Disaster occurred in this coalfield in 1907. Pittsburgh and Castle Shannon Railroad
The Pittsburgh and Castle Shannon Railroad was a narrow-gauge railroad in Allegheny County, Pennsylvania.
 Originally built in 1871, it may have been the first American common-carrier narrow-gauge railroad.
 It purchased a rail line called the Coal Hill Coal Railroad from the Pittsburgh Coal Company, and used a coal mine under Mt. Washington as a tunnel to transport coal from Castle Shannon, Pennsylvania to Pittsburgh.
 Passenger traffic was added soon afterwards, and the train carried passengers during the day and coal at night.
 The original plan was to extend the line to Finleyville, Pennsylvania, but the original narrow-gauge line ran only as far as Castle Shannon.
 The right of way continued as the Pittsburgh, Castle Shannon and Washington Railroad, later to become part of the Pittsburgh Southern Railroad. Pittsburgh and Castle Shannon Plane
Pittsburgh and Castle Shannon Plane was a narrow gauge incline railway that ran from the northern end of the Pittsburgh and Castle Shannon Tunnel to Carson Street in Pittsburgh, Pennsylvania.
 Originally built to carry coal from the Jacob Beltzhoover mine, it was sold by the Pittsburgh Coal Company to the Pittsburgh and Castle Shannon Railroad in 1871.
 It was used only for coal as early as 1864, passenger traffic was added in 1874 for the Pittsburgh and Castle Shannon Railroad.
 For safety reasons, the tunnel was closed to passenger traffic, and passengers were diverted to the Castle Shannon Incline, constructed in 1890.
 Emergency use of the plane for passengers and freight continued as late as 1900.
 Its use for the transport of passengers and freight other than coal was made obsolete by the Mount Washington Transit Tunnel.
 Operation as a coal incline continued until May 1, 1912.
