Along the Old Main No-17 - 'Diesels in the Trees'

A westbound CSX freight train rumbles along the Patapsco River
on the Old Main Line near the town of Sykesville, Maryland.

The "Old Main," built by the Baltimore and Ohio, was the first commercial railroad line in the United States,
the first section opening in 1830. It diverges from the Baltimore to Washington mainline at Relay, and continues
58.5 miles as a single track (but with passing sidings) through the forests and craggy terrain of the Patapsco River
Valley, through central Maryland to Point of Rocks (Washington Junction). There, at an iconic B&O built station (**),
it joins the modern mainline, the Metropolitan Branch, to head west.

The Old Main once saw passenger service, but even those meandering steam-powered locals would
disappear in the years following World War Two. The Old Main is now entirely a freight operation, with the
exception of a MARC commuter service to Frederick operating on a short stretch from Point of Rocks.
