St. Kitts, one of the smallest nations on earth, still runs a narrow-gauge railway along nearly 30 kilometers of coastline, and this film follows the line from its origins as sugar cane infrastructure to its second life as a tourist attraction. Local plantation owners built the track between 1912 and 1926 to haul cane to the factory in Basseterre, but when European sugar beet undercut Caribbean cane, freight traffic died out and the American-owned St. Kitts Scenic Railway took over, catering mostly to cruise ship passengers. The film shows how the new operators repurposed locomotives originally built to move sugar beet in Poland, now pulling double-decker carriages with open views of the sea and mountains. Most of the old cane-era engines have rusted away in the humidity along with the shuttered factory, except for the No. 15 Hunslet locomotive, still used for track and bridge maintenance. Its engine driver narrates memories of when it was the fleet's most powerful machine, hauling wagons stacked with cane, as the crew retraces the old sugar route by rail.
