Punta Alegre Sugar Company


Class Details by Steve Llanso of Sweat House Media

Class 8 (Locobase 14926)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 64, p. 382. Works number was 52320 in September 1919 and 53656 in September 1920.

Given the available information, Locobase cannot determine to which of the sugar centrals owned by PASC the first of these oil-burning plantation Moguls was sent. PASC was incorporated in Delaware in 1915 by the Atkins family. At its height, the North American owned holding company controlled the Baragua (Camagney), Baguano (Oriente), Caracas (Oriente), Florida (Camagney), Macare'o (Camagney), Punta Alegre (Camagney), San Agustfn (Santa Clara), San German (Oriente), and Tacajo (Oriente).

The specifications would have suited any of the Centrales. Rails weighed between 60-65 lb/yard (30-32.5 kg/metre). Maximum grade against the load was 0.7% and minimum curves were 12 degrees (radii of 315 feet/96 metres). A year later, an identical engine was delivered directly to the Punta Alegre.
