Projektstudie
Since 2006, Indonesian authorities have expressed an interest in high-speed rail for the densely populated island of Java, probably linking the cities of Jakarta, Bandung, and Surabaya. Since 2008, government with Japan International Cooperation Agency (JICA) and Japan Transportation Consultant has done pre-Feasibility study. The Jakarta-Surabaya 685-kilometre fast train will connect both cities in 2 hours 53 minutes with maximum speed 350 kilometres/hour and average speed 300 kilometres/hours. The construction project will need 14.3 billion, exclude land acquisitions and detail engineering design, so the total cost predicted was $20 billion.
