Guanoco & La Brea 2-8-2 Locomotives in Venezuela


Class Details by Steve Llanso of Sweat House Media

Class 10 (Locobase 14196)

Data from Baldwin Locomotive Works Specification for Engines, 1890, as digitized by the DeGolyer Library of Southern Methodist University, Vol 49, p. 118. See also the breathless New York Times article "THE ASPHALT LAKE IN VENEZUELA; Deposit of Pitch Inexhaustible and Should Last for Ages. HUGE BLACK SEA OF WEALTH Its Value Almost Incalculable -- Some Data Regarding the Locality Where the Present Trouble Prevails -- Foreigners Not Welcome There.", New York Times, 1 February 1901. See also C N Forrest, "Production of Trinidad and Bermudez Lake Asphalts," Better Roads and Streets, Vol 5, No 8 (August 1915), p. 25-30+. Works number was 40953 in November 1913.

The development of this lake was spearheaded by the New York & Lake Bermudez development company. Extraction of the asphalt was an involved process that included a 7-mile trip by train, where this little Mikado came into play. The tracks curved as sharply as 22 degrees (262 feet/79.9 metre radius) and rail weights were a modest 45 lb/yard (22.5 kg/metre).

After only a few years, the G & LB sold the 20 to Nevada's Uintah Railroad in June 1919 as their 3. They later renumbered the engine #40.. After another 20 years, the Uintah sold the 40 for scrap.
