Michigan Railroad Lines covers each of Michigan's "steam" and electric railroads, detailing every main and branch line of every railroad corporation that operated in the state by giving the stations and mileage of each. This detail also includes a list of the owners of each line. A chronology of the construction and abandonment of each line is included along with the changes in its mileage. For each railroad company there is a summary of all of the construction and abandonment and changes of mileage throughout its corporate life. The mileage of each company is brought together in a year-by-year table of railroad mileage in the state. A set of maps for each county in the state as well as several more detailed city maps show the extent of Michigan's railroad network.
