Data from DeGolyer, Vol 72, pp. 100+, Works number was 58135 in December 1924.
All of the railway's name shown in the specifications was lettered onto the side tanks of this oil-burning freighter. They referred to the extension of the Supe-Barranca by 26 km (16.1 miles) to the Alpas estate, connecting the latter to the port of Supe.
According to the Bulletin of the Pan American Bulletin of 1911 (p. 808), the extension would "thus be an important factor in developing the surrounding country, and in affording more adequate facilities for transporting the increasing agricultural and stock-raising products of the fertile valleys of Barranca and Pativilca." These river valleys empty into the Pacific about 175 km (109 miles) north of Lima.
The line was lightweight--20 lb/yard (10 kg/metre) rail--, tight (curve radii as small as 65.6 feet/20 metres), and steep in places (3 1/2% grades).
