MRTJ 1000 series

The trains built by Nippon Sharyo under Contract CP108, legally known as the MRT Jakarta K1 1 18 series and colloquially known as the MRT Jakarta 1000 series "Ratangga", are the first rolling stocks to operate in the MRT Jakarta system. All sets--legally classified as executive-class trains by the Ministry of Transportation (hence the "K1")--were built in 2018 and started operation on 24 March 2019.
History.

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. It offers a women-only carriage during morning peak hours from 7AM to 9AM and in the afternoon from 5PM to 7PM.
