CSX/B&O Halethorpe Interlocking (HX Tower) - relocated

 railway, interlocking tower

Halethorpe was a major B&O Railroad interlocking tower. South and west bound traffic was switched between the Old Main Line and the Washington Branch at the Halethorpe Interlock. HX Tower was built in 1917, closed Oct. 1, 1985, and remains the last surviving control tower on the Old Main Line.

HX tower demarks the beginning of the CSX Old Main Line Subdivision, extending 59 miles west to Point of Rocks, MD and presided over a 4-track full crossover with B&O CPL gantries at each end. The interlocking was removed and relocated about .5 miles to the south at St Denis in conjunction with a capacity improvement project.

The CSX Baltimore Terminal Service Center (BTSC) in the CANCO building at the corner of Halethorpe Farms Rd and Hollins Ferry Rd closed when dispatch operations were centralized in Jacksonville, FL. CSX returned its local dispatch operations to Baltimore on June 21, 2008 when it opened its new Baltimore Dispatch Center in the former Carling Brewery plant on the southwest side of the Baltimore Beltway.
