Gending Sugar Mill Articulated Locomotives in Indonesia
Class Details by Steve Llanso of Sweat House Media
Class 4 (Locobase 6389)
Data from h[
], the Frankfurter feldbahn museum website. Unfortunately, none of the diagrams give the cylinder measurements. Works number was 3902 in 1909.
O&K delivered this engine to a sugar mill on the island of Java, where the little articulated worked for 70 years. Except for its size, the engine was orthodox Mallet with its front engine set pivoting on a point behind the drivers, large cylinders in front, HP behind.
After the mill retired its doughty little helper, the Frankfurter Feldbahn Museum bought the locomotive and had it shipped to Frankfurt. The container was unloaded on 15 October 1997.
