|---|---|---|---|
 B&O's overhead third-rail system at Guilford Avenue in Baltimore, 1901, part of the Baltimore Belt Line. The central position of the overhead conductors was dictated by the many tunnels on the line: the ∩-shaped rails were located at the highest point in the roof to give the most clearance[1] | |||

The Baltimore Belt Line was constructed by the Baltimore and Ohio Railroad (B&O) in the early 1890s to connect the railroad's newly constructed line to Philadelphia and New York City/Jersey City with the rest of the railroad at Baltimore, Maryland. It included the Howard Street Tunnel, the Mount Royal Station for B&O's Royal Blue Line passenger trains, and the first mainline railroad electrification in the United States. CSX Transportation currently operates the line as part of its Baltimore Terminal Subdivision.
