The railway was originally constructed circa 1915 and was fully operational until the late 1990s, with over 300 kilometres (190 mi) of track in the Perhutani forests.
The railway is popular with foreign tourists, especially from Europe, the United States and Japan.
The main remaining line is of a distance of around 30 kilometres (19 mi) to an arboretum where there are spectacular 150-year-old teak trees along with a visitor centre where tourist train passengers are often entertained by local cultural shows.
Tours and charter trains are marketed and run by PT Palawi, a subsidiary of Perhutani, in Jakarta.
