The railroad was originally incorporated as the Baltimore & Sparrows Point Railroad Company.
Bethlehem Steel took over the railroad in the early 20th century. In 1916, the railroad was renamed the
Patapsco and Back Rivers Railroad. The PBR operated until 2012 when the
steel mill closed down; however, in 2014 the remainder of the railroad was bought by
Sparrows Point Terminal, LLC (SPT) and named The Baltimore Industrial Railroad. In January 2016 the railroad was renamed Tradepoint Rail (TPR), a part of the Tradepoint Atlantic family of companies. The rebuilt system has of track, the largest privately owned
rail yard on the East Coast, access to
Norfolk Southern Railway and
CSX Transportation, and a fully operational locomotive shop capable of major repairs. Steel was the main commodity hauled during the era of the steel mill, but currently most revenue comes from tank car storage. ==Locomotive Roster==
