Trujillo 2-8-0 Locomotives in Peru
Class Details by Steve Llanso of Sweat House Media
Class 22 (Locobase 4583)
Data from Dr Jonathan Smith, [
] . A Ziel & Eagleson (1973) photo from the early 1970s showed a sturdy little Consolidation. (Thanks to Richard West for his 25 September 2021 email correcting the wheel arrangement and reporting the details about the builders and road numbers.) According to Copeland's roster--works numbers were 1795 in 1936, 3413 in 1947, and 3868 in 1956.
Hunslet supplied the Trujillo with these three Consolidations over a 20-year period. In 1948, the Peruvian Government transferred the 30 (the renumbered 22) and 31 to the F. C. Huancayo a Huancavelica, which renumbered them 107-108. Apparently, the national system decided the Trujillo needed a new 2-8-0 and bought the 32 from Hunslet in 1956.
