The Atjeh Tram was a railroad line in Aceh, on the island of Sumatra. It was built from 1874 by the Military engineering section of the Royal Netherlands East Indies Army (abbreviated "KNIL" in Dutch). Originally a loop for the port of Oleh Leh, it was rebuilt as a route for the transport of military goods stretching from Ule Lheu to the port of Pangkalan Susu in the Sultanate of Langkat. The line was 511 kilometers long, with 120 stops and stations along the way. It was finished in 1917. During the Aceh War the railroad proved of great importance for the quick transportation of troops and material.
