An electric train maintenance facility in Depok, West Java, was officially opened by President Susilo Bambang Yudhoyono on Tuesday.
The President spoke via remote link-up from Kutoarjo in Central Java.
West Java Governor Dani Setiawan, who attended the launch, said the 26-hectare facility was the largest train depot in Southeast Asia.
Extending 1.3 kilometers in length and 200 meters in width, it has 14 stabling lines that can accommodate up to 224 trains.
The area also contains large office and maintenance buildings, as well as 30 rooms with 120 beds for train drivers and engineers.
The depot was constructed between Aug. 2004 and Aug. 2007 at a total cost of Rp 504 billion, which was provided in state budget allocations and through Japan Bank for International Cooperation loans.
"This way we can maintain our trains better and improve our services for the city's commuters," said Harijogi, the general secretary of the Ministry of Transportation.
Akhmad Sujadi, the spokesman for the Greater Jakarta branch of state-owned railway company PT Kereta Api, said 402 electric train services were offered in the Greater Jakarta area, including between the capital and Bekasi, Bogor, Depok and Serpong.
"We plan to add 56 more services this year," he said.
The President was in Kutoarjo to launch a 64-kilometer double-track railway line connecting Kutoarjo in Central Java and Yogyakarta.
