Guanta-Barcelona 2-6-2 Locomotives in Venezuela


Class Details by Steve Llanso of Sweat House Media

Class President Gomez (Locobase 15474)

Data from DeGolyer, Vol 79, pp. 683+. See also the account at [link], last accessed 12 October 2013. Works number was 61821 in October 1934.

All of the specifications for this low-drivered Prairie tank used metric measurements. This was a simple design based on Baldwin's smallish logging Prairie tank, but had even more modest dimensions. It burned low-calorie coal briquettes, which accounts for the relatively large grate area.

This railway began after the completion of the docks and quays at the Port of Guanta by the British-owned Guanta Railways Harbour & Coal Trust Company Limited in December 1886. By 1890 the Guanta depot boasted four locomotives, four first-class carriages, six second-class, two mixed-class, three closed freight waggons and six open-top as well as 85 coal cars. The railway covered 19.3 km (12 miles)
