Two cape gauge, oil-fired Consolidations joined the Sibambe-Cuenca eight years apart. The 2 was later sold to the Guayaquil a Quito as their 45 and 4 was renumbered 17 by the GaQ.
See Locobase 948 for the superheated sister to this engine.

This oil-fired cape gauge Consolidation joined two larger Baldwin-built Consolidations (Locobase 14506) on the Guayaquil & Quito Railway Co for the FC Sibambe-Cuencda, a railway that measured 110 kilometres (70 miles) between the two Ecuadorian towns and took 57 years to build. By the time this locomotive was delivered, construction had reached Azogues.
The engine's firebox heating surface area included 12.6 sq ft (1.17 sq m) and cylinders received their steam from 8" (203 mm)
