This is an MTA Blue Line (LA to Long Beach) train, outbound to Long Beach near Flower and 17th. The freeway overpass above the train is the I-10 (Santa Monica) Freeway, looking northbound from the intersection.
This photo was taken in approximately 1998-1999, when I was still working for the LAPD Transit Bus Division; I was one of the first units to roll up on the scene.
At this particular location, as the train travels along Flower (heading toward the junction with the old PE Right of Way at Washington and Long Beach Ave), the street is all way one traffic, southbound. There are a few crossings over the tracks where traffic can either turn into driveways for businesses, or in this case, there is a freeway entranceway just to the right, out of camera, to an onramp for the eastbound 10 Freeway.
There have been a number of accidents in the same stretch of road, because drivers get impatient, and don't want to wait for the red left turn arrows to turn green, so they run the lights. At this writing, in spite of 10 years since streetcars returned to the Blue Line, it only runs along Flower and Washington streets in downtown, and the trains are still somewhat of a novelty.
