Data from Negative No P-481, Class 060-38 built for the FPMRR, American Locomotive builder's card Martin Coombs, Part 6: Ecuadorian steam locomotive list from his Railways of the Far South series, v.1.24 (March 2026), p.93 on the web at [], last accessed 7 March 2026. Works number was 29966 in 1904.
Manabi railroad construction began in 1904 and extended "several kilometres from Puerto Larrea", reports Coombs, and this little all-adhesion freight locomotive may have constituted its entire motive power roster.
