Central Azucarera de Bais 0-6-0 Locomotives in Philippines


Class Details by Steve Llanso of Sweat House Media

Class 1 (Locobase 14745)

Data from DeGolyer, Vol 63, pp. 209 and Vol 78, pp. 340+. See also a listing of Sugar Centrals in the Philippines in the American Chamber of Commerce of the Philippines Journal (January 1922), p. 30. Works numbers were 53630-53631 in September 1920 and 58780 in October 1925.

Bais opened in May 1919 and soon reached 1,000 tons of sugar per day. These saddle tankers could be run alone or with the tender with which they were delivered. All three held 400 US gallons (1,514 litres) in the saddle tank. The first two pulled 500 gallons (1,893 litres) in the tender. The third engine pulled a larger tender with 900 gallons (3,407 litres).


Class 7 (Locobase 15406)

Data from DeGolyer, Vol 78, pp. 343. See also a listing of Sugar Centrals in the Philippines in the American Chamber of Commerce of the Philippines Journal (January 1922), p. 30. Works number was 58779 in October 1925.

As might be expected, plantation locomotives were often specified to be reinforced and this locomotive's springs and spring hangers were to be "extra heavy."
