Baltimore Belt Line pulled by horses along Pratt Street between the B&O's Camden Station and the PW&B's President Street Station. In 1884, the PW&B was purchased by the Pennsylvania Railroad (PRR), a major rival of the B&O, and the PRR cut off the connection. The B&O then proceeded to build its Philadelphia Branch (formally known as the Baltimore and Philadelphia Railroad) to connect to the Philadelphia and Reading Railroad, in turn connecting with the Central Railroad of New Jersey for B&O's New York service. The combination also provided a connection to the Staten Island Railway, which served as the terminal switching company for
Frederick and Pennsylvania Line Railroad Company Haydon to resurvey road location from Littlestown to the state line. Haydon completed his resurvey and in December,1869 the Board approved relocating the line from Gitt's alignment along Israel Creek (the east-side route) thru Woodsboro, Walkersville and into Frederick city to Haydon's west-side alignment along Glade Creek. The Board ordered a review on the Harmony Grove segment in the Spring of 1870, but by the fall of 1870, Haydon's resurvey was complete and on September 27, 1870: Haydon presented his report on the west and east line location study with the east line in Frederick city connecting with the B&O
