History
Contract CP 108 for the procurement of rolling stock for the Jakarta MRT was awarded to a consortium led by Sumitomo Corporation, on 3 March 2015.[1] 16 six-car trainsets were ordered at a cost of ¥10.8 billion (Rp. 145 billion).[2] The trains were built in Nippon Sharyo's Toyokawa, Aichi plant.[3]
Specifications
Each car measures 20 m (65 ft 7 in) in length, 2.9 m (9 ft 6 in) in width and 3.9 m (12 ft 10 in) in height.[4] These trains utilizes CBTC signaling system and are equipped with Automatic Train Operation (ATO) GoA 2, with drivers operating the doors and driving in case of emergency.[5] Like the KRL Commuterline, the MRT trains are also powered via overhead catenary.[6]
Naming and service
On 10 January 2018, the Governor of Jakarta, Anies Baswedan gave the first batch of MRT Jakarta trainsets the name "Ratangga". The name was derived from the old Javanese word for chariots.[7] It offers a women-only carriage during morning peak hours from 7AM to 9AM and in the afternoon from 5PM to 7PM.[8]
