Calvert Street Station served railroad passengers of the Northern Central Railway in Baltimore, Maryland, from 1850 until 1948. It served as the terminus for the second railway chartered in Maryland, which eventually was expanded into a network containing nearly 400 miles of track. The Northern Central, always in financial trouble, was leased by the Pennsylvania Railroad (PRR) after 1861. With the opening of nearby Pennsylvania Station, the terminal became redundant. Rail traffic ceased around 1948 and the station was razed in 1949 to make way for the current occupant of the space, The Baltimore Sun.
