It looks like the new Mass Rapid Transit is over 90% complete and set for an early 2019 launch.
Jakarta, Indonesia’s massive capital city has some of the world’s worst traffic congestion. There are several measures in place to help reduce traffic, but one of the best is coming soon.
The initial line is on schedule to open in March and will stretch 15.7 km from Lebak Blusu in the south to central Jakarta. The MRT will provide a 30 minute option for a trip that currently takes two to three hours.

The city looks to provide a modern, public train system servicing the entire city with three or four more lines in the planning stages.
