The Ludington and Northern Railway, also known as the Dummy Train, or the L&N, is a defunct railroad which operated in Mason County, Michigan between 1902 and 1982.

At a length of 2.79 miles (4.49 km), it was for decades the shortest operating common carrier railroad in the state.

The original line completed in 1896 was 2 miles (3.2 km) long, running from Ludington to Epworth Heights, a Methodist Church summer colony.

On July 18, 1901, the name was changed to Ludington and Northern Railway when Justus Smith Stearns purchased it.

The Sargent Sand company shortened the route, terminating it at their 79.6-acre (32.2 ha) mining operation, at which point the railroad reached its final length of 2.79 miles (4.49 km).
