Links marked with S or T include historical information on lost passenger Stations and interlocking Towers. Information on towers serving multiple railroads is not directly duplicated, but instead linked to a relevant page for the primary operating railroad.
Lines are grouped into historic operating divisions. As passenger service declined during the 1950's, many divisions were consolidated.
