Data from catalogue illustration reproduced on narrowmind.railfan.net. See also DeGolyer, Vol 79, pp. 188. These had Baldwin works 60100-60101 in July 1927.
The photo shows a high-pitched boiler, straight stack and three bell-like domes. Firebox heating surface included 13 sq ft (1.2 sq m) of arch tubes. Normally the actual measurement of the engine and tender wheelbase fell a few feet short of the limitation shown in the specification. This pair took advantage of every quarter inch and came out just that much short of the 52 foot, 6 inch (16 metre) boundary. An order to the Extra Work Department required that the tender be "arranged for application of 2,000 gallon [7,570 litre] oil tank."
The railroad had its ups and downs in many ways. The Baldwin specification noted that the class was "to operate at an altitude of 15,000 feet.[4,572 metres]." According to the Peruvian railroad website [] , accessed 21 July 2007: "It is called the Tough Train because 'it leaves when it wants and arrives when it can'. It is one of the only railways that still belongs to the State. It is 148 km [92 miles] long and has a gauge of 0.914 mm. The first 77 km [47.8 miles] were opened for traffic in 1926 and the rest in 1933." At various times, it was known as the FC Huancayo-Ayacucho (at which time the first engine had the name shown in the specs) and later as the Huancayo - Huancavelica Railway.
