The island Commonwealth of Dominica should not be confused with the Dominican Republic, which forms the eastern part of the island of Hispaniola.
A steam hauled, 3 foot (914mm) gauge railway was built on Dominica some time before 1910 by a forestry company for the purposes of carrying timber the port of Portsmouth. The line had been abandoned by 1914.
