In July 1870, Casement was part of an effort to reconstruct the Union & Titusville Railroad from wide gauge (6'-0") to standard gauge at an estimated cost of one million dollars. The railroad planned to reconstruct its track Financing for the project was to be a mix of existing funds in the corporation ($250,000) with the remainder of the funding to be provided by the Casement brothers in exchange for additional stock or bonds. For about half its length, the railroad ran alongside the Oil Creek and Allegheny River Railway and then onto Union Mills to connect with the Philadelphia and Erie Railroad.
