1949, freedom fighters took over the railways, creating the first direct predecessor to today's PT Kereta Api, the Djawatan Kereta Api Repoeblik Indonesia (Railway Bureau of the Republic of Indonesia), on 28 September 1945. This date, not the 1867 one, is regarded as the birth date of Indonesian railways and commemorated as Railway Day every year, due to political ground. On the other hand, the Dutch created its own combined railway system to manage the lines located on its occupied territory, the Verenigd Spoorwegbedrijf (Combined Railways). By the time of Dutch recognition of Indonesian independence, the VS had most railway lines under its management, though not all were in operation. With Indonesia's full independence in 1949, the separate systems (except the Deli Railway) were combined into the Djawatan Kereta Api. Non-state railway systems in Java retained their paper existence until 1958, when all railway lines in Indonesia were nationalized, including the Deli Railway, thereby creating the Perusahaan Negara Kereta Api (PNKA: State Railway Corporation) in 1963. On 15 September 1971 the name of PNKA was changed to Perusahaan Jawatan Kereta Api (PJKA, the Indonesian Railway Systems). Later then, on 2 January 1991, PJKA was changed its name and status as Perusahaan Umum Kereta Api (Perumka, the Indonesian Railways Public Company), and since 1 June 1999, this company was changed to a limited company, PT Kereta Api (Persero) (PT KA). In May 2010, the name of "PT KA" was changed to PT Kereta Api Indonesia (Persero) (PT KAI, The Indonesian Railways Company) till present. The headquarters of the state railway system, since Dutch colonial days, had been located in Bandung, West Java. Private railway companies were headquartered elsewhere, in Semarang, Tegal, Surabaya and Medan. Construction of new railway lines has been scarce. In 1997, a line was inaugurated from to in West Java. At the beginning, this line was planned to be incorporated into a larger circular line network, ranging from to . This plan had to be postponed due to the 1997 economic crisis.
