History of rail transport in Indonesia

As befits a colonial enterprise, most railway lines in Indonesia had a dual purpose: economic and strategic. In fact, a condition for the financial assistance for the NIS was that the company build a railway line to [[Ambarawa]], which connected to the one of an important military base named Fort [[William I of the Netherlands|Willem I]] for the Dutch king. The first state railway line was built through the mountains on the southern part of Java, instead of the flat regions on the north, for a similar strategic reason. The state railway in Java connected [[Anyer]] on the western coast of the island, to [[Banyuwangi]] on the eastern coast.

Only in the 1920s did one section, the Jakarta-Bogor line, be electrified with Dutch assistance, it would be the first ever electric rail system in Southeast Asia and the first electric commuter train service there as well.

It was also the first in Southeast Asia to be operated by [[electric multiple unit]]s that would run for 4 straight decades, which would be defined with their European manufacture and their latter green-white livery schemes across these sets that would be adopted by the latter diesel locomotive fleet of its successors.
