Possibly the only engines to run on the Eritrean Railway with any auxiliary axles. At least 32 of this class were built for the Italian State Railways for Sicilian narrow-gauge operations in the teens..Four - 305, 307, 315, and 332 -- were transferred to Mogadishu in 1926-1927. The quartet served the railways for a decade, and then were put in mothballs. Scrapping followed in 1944.
See http://www . trainweb.org/eritrean/scrapbook for much information and many pictures of Eritrean steam. Data taken from November 1969 Trains article reproduced on that site.
