Malden Island
The guano diggers constructed a unique railroad on Malden Island, with cars powered by large sails. Laborers pushed empty carts from the loading area up the tramway to the digging pits, where they were then loaded with guano. At the end of the day, the sails were unfurled, and the train cars whisked back to the settlement by the prevailing southeastern winds. While cars were known to jump the tracks more than once during these excursions, the system seems to have worked fairly well. Railroad handcars were also used. This tramway remained in use on Malden as late as 1924, and its roadbed still exists on the island today.
