Hacienda Roma 0-4-4 Locomotives in Peru


Class Details by Steve Llanso of Sweat House Media

Class Chiquitoy (Locobase 13753)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 36, p. 222. See also Eduardo Salazar, "Los Larco, la Hacienda Roma y el Asilo Colonia de la Magdalena" from the blog Inmigración en el Siglo XIX, Bitácora sobre la inmigraci=n en el Per+, siglo XIX found at [], last accessed 20 January 2012. Works number was 34837 in June 1910.

William H Knox & Company was the dealer that ordered this tank engine from Baldwin. It had a 200-gallon tank on the boiler and 400 gallons in a rear tank. Chiquitoy was able to burn either coal or wood. The specs referred to an earlier 8-12 1/2 C 2 order, but added "Incorporate all improvements due to modern practice to 1910."

Hacienda Roma was so named because the Larco family originally came from Santa Margarita Ligure near Rapallo, some 39 km from Genoa in northern Italy. Salazar tells us (Locobase's translation) that two of the brothers -- Antonio and Andres Larco Bruno -- realized that they wouldn't make their fortunes in growing cotton as readily as they might if they took up the relatively recent craze in sugar-cane growing. They purchased the Hacienda Chiquitoy, which was located in the Chicama valley, in 1872. Comprising 1,250 fanegadas (each fanegada had an area of 1.1 acres, so the total acreage was 1,384), the hacienda was a starting point for a sugar-cane empire once the brothers expanded considerably the acreage devoted to that crop.

1878 saw the acquisition of the Tulape and Cepeda haciendas, which were run by Andres and which he renamed collectively Hacienda roma. Over the next decade (once the War in the Pacific had ended), Hacienda Roma grew to 4,000 fanegadas (ca. 4,400 acres). A family dispute in 1901 resulted in the division of property. Victor Larco Herrera ran the Hacienda Roma from that point on until 1921


Class Paijan (Locobase 14002)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 44, p. 213. See also Locobase 13753 for a description of this sugar barony. Works number was 37579 in March 1912.


Class Paijan (Locobase 14003)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 54, p. 327. See also Locobase 13753 for a description of this sugar barony. Works numbers were 41860-41861 in January 1915 and 42233-42234 in August.

Locobase would usually incorporate these four 1915 radial saddle tanks in the 1912 record of the Paijan (Locobase 14001). But the Salaverry, Moche, Chicama, and Chocope were not only almost three years younger, they were noticeably heavier as well and their heating surface area measurements were both quite exact and very slightly different. All of them were delivered with two types of grates, one on which to burn wood, one to burn coal.
