The Jakarta Kota–Manggarai railway (Indonesian: Jalur kereta api Jakarta Kota–Manggarai), nicknamed the rainbow line (Indonesian: Jalur Pelangi), is an elevated, 15 km long railway line that connects with . Given its central position in the city, it is one of the most important railways in Jakarta.
Between 1871 and 1873, the Dutch railway company Nederlands-Indische Spoorweg Maatschappij built the railway as part of the line to . Originally there were two northern termini, each on a separate rail branch: one next to the former city hall at "Station Batavia Noord", and the other at "Kleine Boom" on the east side of the Sunda Kelapa harbor near current day Pasar Ikan. "Kleine Boom" was the location of a customs office, and therefore this terminus was primarily meant for foreign boat passengers.[1]
Initially built as a standard gauge (which at the time was referred to as 1067 mm gauge) and single-track railway, the line gained a second track and was electrified in the early 1920s in a project to improve the entire Batavian railway network. There had been plans to elevate the line between and, but this was cancelled due to the depression of 1920-21.[2]
Between 1988 and 1992, the so far ground-level railway was reconstructed into an elevated railway after all, aimed at providing grade separation to avoid level crossing accidents with other traffic. The elevated stations were each colored differently, hence the "rainbow line" nickname.
Both intercity and local trains use the Jakarta Kota-Manggarai line. Intercity trains will typically only serve Gambir Station, while local commuter trains call at every station. The following is a list of scheduled trains on this route:
