Quito a Esmeraldas 2-8-0 Locomotives in Ecuador

Class Details by Steve Llanso of Sweat House Media

Class 3 (Locobase 15453)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 79, pp. 308+. See also "The Railroads of Ecuador", The South American, Vol 7, No. 8 (August 1919), pp. 16-17. Works number was 61619 in March 1931.

The contract for this Government-built railway was signed in 1913. At that time, the planned length was 175 miles (282 km). The contractors were Orenstein & Koppel of Berlin and they got off to a slow start (as might be imagined given the terrain and the entrance of Germany into World War One.). Construction began on 28 July 1916 and by July 1917 had progressed 14 km (8.7 miles)

"In many respects," said The South American, "this is one of the most interesting railways projected for Ecuador in recent years. The territory north of Quito, extending some distance beyond Ibarra, is the most thickly populated and richest section of Ecuador. Ibarra is the capital of Imbabura Province, and from this city the line will turn westward, pass through the 'salinas' on the margin of the forest, and thence proceed down a virgin tropical terrain to the coast."

An oil-burning, superheated Consolidation with 8" (203 mm) piston valves, the 3 rolled on 41 lb/feet (21 kg/metre) rail and faced 4% grades and curves as tight as 29 degrees (radii of 197 feet/60.2 metres).
