In July 1897, a new company called the Chicago Terminal Transfer Railroad (CTT) bought the C&NP from the Wisconsin Central. While the WC (and successor Soo Line Railroad) no longer had its own direct connection to the city, it continued to use the line to access Grand Central Station until 1899, and between 1912 and 1965. In May 1897, the Chicago Terminal Transfer merged the Chicago & Calumet Terminal. The B&O began using Grand Central Station in 1892, when a connection was made between the CTT and the B&O at South Chicago. When the Pere Marquette Railroad was completed to Porter, Indiana in 1903, it also used the CTT into Grand Central Station.
