The Detroit, Toledo and Ironton Railroad operated from 1905 to 1983 between its namesake cities of Detroit, Michigan, and Ironton, Ohio, via Toledo. At the end of 1970, it operated 478 miles of road on 762 miles of track; that year it carried 1,244 million ton-miles of revenue freight.
The Pittsburgh and Lake Erie Railroad, also known as the "Little Giant", was formed on May 11, 1875. Company headquarters were located in Pittsburgh, Pennsylvania. The line connected Pittsburgh in the east with Youngstown, Ohio, in the Haselton neighborhood in the west and Connellsville, Pennsylvania, to the east. It did not reach Lake Erie until the formation of Conrail in 1976. The P&LE was known as the "Little Giant" since the tonnage that it moved was out of proportion to its route mileage. While it operated around one tenth of one percent of the nation's railroad miles, it hauled around one percent of its tonnage. This was largely because the P&LE served the steel mills of the greater Pittsburgh area, which consumed and shipped vast amounts of materials. It was a specialized railroad, deriving much of its revenue from coal, coke, iron ore, limestone, and steel. The eventual closure of the steel mills led to the end of the P&LE as an independent line in 1992.
The Pittsburgh, Cincinnati, Chicago and St. Louis Railroad, commonly called the Pan Handle Route, was a railroad that was part of the Pennsylvania Railroad system.

The Pittsburgh and West Virginia Railway was a railroad in the Pittsburgh, Pennsylvania, and Wheeling, West Virginia, areas. Originally built as the Wabash Pittsburgh Terminal Railway, a Pittsburgh extension of George J. Gould's Wabash Railroad, the venture entered receivership in 1908, and the line was cut loose. An extension completed in 1931 connected it to the Western Maryland Railway at Connellsville, Pennsylvania, forming part of the Alphabet Route, a coalition of independent lines between the Northeastern United States and the Midwest. It was leased by the Norfolk and Western Railway in 1964 in conjunction with the N&W acquiring several other sections of the former Alphabet Route but was leased to the new spinoff Wheeling and Lake Erie Railway in 1990, just months before the N&W was merged into the Norfolk Southern Railway.

The Pennsylvania Petroleum Railroad was a railroad in Pennsylvania originally chartered in 1871, during the Pennsylvania oil rush. Intended to provide an additional outlet from the Pennsylvania oil fields to Erie, Pennsylvania, it graded about ten miles of line in 1872, but was then caught up in the collapse of the Atlantic and Great Western Railroad, which halted the project. The company was foreclosed and reorganized under new names many times, but accomplished relatively little. It laid a short segment of line in 1890 in Titusville, Pennsylvania which was leased to a subsidiary of the New York Central to be used as a siding to a tannery. Further construction took place in 1913 with the idea of opening it as an electric railway to Cambridge Springs, but this, too, was never completed.
