Chartiers Branch

It is 23.6 miles (38.0 km) long and construction was completed in 1867 and is still in use today, after passing through at least seven different owners.

The road foreclosed in 1861, and the Right of Way was sold to William Howard a solicitor for the Pennsylvania Railroad (PRR).

In 1867, the Chartiers Railway Company was founded, and with PRR backing finished the line.

The line was leased to the Pittsburgh, Cincinnati and St. Louis Railway (PC&StL) on December 8, 1871.

The Pittsburgh, Cincinnati, Chicago and St. Louis Railroad (PCC&StL) gained the lease when it was formed and acquired the road on November 20, 1907.

On August 4, 1959, the connection with the main line at Carnegie was abandoned for a short run over the Pittsburgh, Chartiers & Youghiogheny Railway trackage rights.

The Penn Central, as it did for much of its main and secondary track, let the branch fall into disrepair.
