Lake Superior and Ishpeming Railroad

By 1955 the only passenger service remaining was a single daily train from Munising to Princeton; Marquette and Big Bay were no longer served.

[citation needed] A line between Humboldt and the Republic Mine (part of the Marquette Iron Range) was abandoned and railbanked in 2004.

[4] As of 2016, the Lake Superior & Ishpeming's primary remaining business continued to be the transport of iron ore over a 16-mile (26 km) short line from the Tilden Mine south of Ishpeming, operated by Cleveland-Cliffs, to Lake Superior for transport.

Tonnage was declining sharply due to the shutdown of the adjacent Empire Mine, also historically served by the LS&I.

[5] The Lake Superior & Ishpeming's historic main line operates on a relatively steep grade, called "The Hill", from Marquette to the iron mines.

The LS&I's nicknames have included "Hayden's Scheme," "The Hook and Eye," "Little Sally and Imogene" (after the names of two daughters of H. R. Harris, its first general manager), and "Lazy, Slow, and Independent".
