Most Java sugar mill stream locos are designated as tank engines but run with a tender. This is because the fuel frequently used is bagass, the dried residue after the sugar has been extracted from the cane. This has a low calorific value so large quantities must be carried to keep the loco in steam for a shift. The wood burning locos have a similar but no so serious problem.
