Class Details by Steve Llanso of Sweat House Media

Class 4 (Locobase 14841)

Data from DeGolyer, Vol 64, pp. 90. See also Louisiana Planter and Sugar Manufacturer, Vol 50, No 15 (12 April 1913) , p. 233. Works number was 52086 in July 1919.

The Central El Pilar opened at Artmesia in La Habana Province. In 1913, the LPSM report presented a tepid assessment of the complex: "Pilar is another old-fashioned mill,

housed in a low, rambling tangled sort of a factory building scornful of the principles on which more moder mills arrange their processes, to make the most of time, space and gravity. We read that the arrangement followed here is that of the first sugar factory in Egypt."

Six years later the CEP bought this small plantation saddle tank from Eddystone in 1919. Its specifications envisioned operation on 56 lb/yard (28 kg/metre) rail that was laid on "spongy ground, in bad shape." There were challenges in the profile including the 1 km (0.6 mile) long grade rising at 2% and another 2 km (1.2 miles) run of 1 3/4%.

After the 1959 Revolucion and expropriation, El Pilar was renamed for Eduardo Garcia Lavendero.
