Data from D[ennis] Rock Carling, 4-8-0 Tender Engines, (New York: Drake Publishers, Inc, 1972) p.76 and serial 211 in Table XII [12], pp. 106-107. See also "Locomotora del FC del Noroeste del Per ", posted 23 April 2013 on the Trenes del Peru blog at [], last accessed 1 September 2019.
The Twelve-wheelers delivered in 1911 were the first four engines on the Noroeste, which opened in the same year. The narrow-gauge railway's alignment paralleled that of the Central of Peru from Callao to Lima, but then veered off northwest to arrive at Ancon on the coast, proceed to Huacho, then turn back inland to climb up to Sayan.
Carling's data includes only the rigid wheelbase of 7 ft 2 in (2.19 m), which most likely refers to the second and third coupled axles. That was a feature of a freight design that was expressly designed to handle the tight curves laid out for this railway on the climb to Pasamay, which lay between Ancon and Huacho. The quartet--Lima, Chancay, Huacho, Ancon--apparently satisfied requirements because two more, Jalentre and Hamilton, were delivered in 1923 and 1926.
