Barranquilla Railway & Pier 2-6-0 Locomotives in Colombia

Class Details by Steve Llanso of Sweat House Media

Class 12 (Locobase 10427)

Data from "'Mogul' Locomotive for South America", The Locomotive Magazine, Vol IX (26 December 1903), p. 371.

The BR & PC was an 18-mile railway between Barranquilla and Puerto Colombia that had sharp curves (230-ft radius) and steep grades. To accommodate the tight alignment, the leading truck had radial axleboxes and the middle coupled axle's wheels were flangeless. Despite the impediments, business was described as "heavy and profitable"in 1912.
