Jakarta — State-owned airport operator PT Angkasa Pura (AP) II said it plans to use three more train sets of sky train in the Soekarno-Hatta International Airport in September 2018 to improve mobility of passengers from one terminal to the other. President Director of Angkasa Pura II, Muhammad Awaluddin said currently the country’s largest airport has three sky trains with a carrying capacity of 176 passengers. With the additional units, the airport will have 6 train sets with a carrying capacity of 352 passengers in one way trip. The additional train sets are needed considering the growing number of air passengers from year to year and 80 percent of the users are air passengers, Awaluddin said. “Sky train is a model of crew-less vehicles using automated guideway transit system. The Soekarno-Hatta airport is the first to use sky train in Indonesia starting September 2017,” he said. Currently, the Soekarno-Hatta International Airport has three train sets operating in dual tracks (Tracks A and B) 3.07 kilometer long. The train sets have a maximum speed of 30 km per hour with a headway of 13 minutes and dwell time of 1 minute. The sky train, however, is still operated manually with a crew. AP II plans automation of its sky train to operate the train set without crewmen and the speed would be increased with headway reduced from 13 minutes to 6 minutes so that the frequency of the train trips would increase. The route of sky train is from Terminal 1 – airport railway station – Terminal 2 – Terminal 3 and back. The route would also be made longer to Terminal 4 to be built in the Soewarna golf course area and the commercial area of the sky city is yet to be built. AP II also plans to build and provide supporting facility such as sky bridges, crossing, shelter and signal system. “The progress in the construction of the crossing and shelter has been 100 percent for the first phase, and development of the automatic signal system is nearly completed,” Awaluddin said. With the plan to expand the sky train, the minimum connecting time (MCT) would then be more efficient, he added.
