Class Details by Steve Llanso of Sweat House Media

Class Pimentel (Locobase 11815)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 11, p. 219. Works number 6742 in May 1883.

The P & C planned 45 miles, but when this engine was headed to that line, only 30 were in operation from the port of Pimentel on the Pacific to the sugar capital of Chiclayo.
