Answer: What is Chicago, Rock Island and Pacific Railroad mean?

The Chicago, Rock Island and Pacific Railroad (CRI&P RW, sometimes called Chicago, Rock Island and Pacific Railway) (reporting marks CRIP, RI, ROCK) was an American Class I railroad. It was also known as the Rock Island Line, or, in its final years, The Rock.

At the end of 1970, it operated 7,183 miles of road on 10,669 miles of track; that year it reported 20,557 million ton-miles of revenue freight and 118 million passenger-miles. (Those totals may or may not include the former Burlington-Rock Island Railroad.)

The song "Rock Island Line", a spiritual from the late 1920s first recorded in 1934, was inspired by the railway.
