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 High-Speed Rail is 685 km (425 mi) long. It will connect both the cities in 35 minutes (compared with current 2 hours 53 minutes) with a maximum speed of 350 km/h and average speed 300 km/h. The construction project will need 14.3 billion, exclude land acquisitions and detail engineering design, so the total cost predicted was $20 billion. In July 2015, Indonesian Government revealed their plan to build high-speed rail in Indonesia. Japan and China competed to win the project, previously both nations have done comprehensive studies on the project. On late September 2015, Indonesia awards this multibillion-dollar railway project to China. On 16 October 2015, Indonesia and China signed an agreement to build Jakarta-Bandung High-Speed Rail as first phase of the project. Groundbreaking has been done on 21 January 2016. The project has 60% of Indonesian consortium and 40% of China Railway International. The project is 90% completed as of fall 2022, and is expected to begin its operations in the end of 2022. The two governments are in talks to resolve the (US $) cost overrun for the first section. Completion of the next phases of the project to Cirebon, Semarang, and Surabaya is uncertain given that the capital's relocation and completion of the Trans-Java highway might affect demand. However, the Indonesian Transportation Ministry has outlined the construction of high-speed rail to Semarang as a priority as of spring 2022. Iran Iran has a high-speed rail under construction connecting three major cities of Tehran, Qom and Isfahan. The line will have a station in Imam Khomeini International Airport. The route length will be 422 km (262 mi) with the operating speed of 350 km/h, decreasing the travel time from 5 hours to 90 minutes. The project costs over 7 billion Euros and will be open in 2022, built by China Railway Engineering Corporation. A 117 km (73 mi) double track branch from Qom to Arak will be built for 300 km/h headway at 1.2 billion euros (including Arak station and 6 viaducts), a contract which the Islamic Republic of Iran Railways initially awarded to Italian-based Ferrovie dello stato in 2017, but was reawarded to Chinese corporations following enforcement of US-led sanctions in 2018, alongside many other rail
