SLM HGm 4/6 BB204 Locomotives – Indonesia

The BB204 is a Swiss-built diesel-electric locomotive developed by Schweizerische Lokomotiv- und Maschinenfabrik (SLM) for the steep railways of West Sumatra. Known as the HGm 4/6, it combines conventional adhesion running with rack equipment for the region's demanding mountain routes. The class helped replace E10 steam locomotives on the railway serving the Ombilin coalfields, giving it a special place in Indonesian railway history. This pack includes eight selectable variants in PJKA, Perumka and KAI liveries, covering the early and 1993-style models along with GANCO coupling variants.  Original models by BY87. Transport Fever 2 port by Daffarifky and AveMariaX. Transport Fever 3 adaptation by Jason0977.
