Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 72, p. 91 and Vol 78, pp. 207. Works numbers were 58011 in September 1924 and 59205-59206 in May 1926.
These small Mikados were some of the lightest and smallest 2-8-2s to operate on the three-foot gauge; even so, the 3 was half again as big as the two Baldwin Moguls delivered in 1920 (Locobase 15101). Like many of the others on this gauge, the 3 would run on 35 lb/yard (17.5 kg/metre) rails up 4% and around curve radii as tight as 50 metres (164 feet). One truly breath-taking condition to keep in mind was that these engines were operating at 15,000 feet (4,572 metres) altitude.
The 4 and 5 were named "La Convencion" and "Presidente Leguia".
The railway was authorized in 1907 on the 30-in gauge, its first section opened in the early 1920s on a widened right of way. It reached Aguas Calientes about 70 miles (113 km) distant in 1928.
The 3 would later be sold to the Lima a Lurin as their 51.
