Please see the notice and map above. Hours of testing will vary — it’s best to assume these are active tracks and to look both ways and obey all traffic and pedestrian signals.
Also, as reported by Santa Monica Next, the Expo Line Construction Authority handed over the mainline tracks to Metro on Friday. The Authority still must hand over the project’s rail yard in Santa Monica to Metro. Once that happens, an opening date can be set.
The Construction Authority is the independent agency charged with building the project, which was built in two phases. The first segment between downtown Los Angeles and Culver City opened in 2012. The $1.5-billion second phase completes the line to Santa Monica and adds seven new stations. The project was largely funded by Measure R, the half-cent sales tax increase approved by Los Angeles County voters in 2008.
Here are some images of train testing taken in latter half of 2015:
