Last September, took a trip along the under-construction Expo Line, between Downtown LA and Culver City.
Now there are test trains running, but up until about a week ago, the trains ran along the Exposition Bl. segment of the route, where I rarely go anymore.
Last week, however, I started seeing Expo Line cars (similar to the Gold Line vehicles) on Flower St, just south of the junction at Washington Bl.
Enjoy the pictures, and I hope to see the Expo Line cars testing at 7th/Metro Station real soon….

Looking northward on Flower towards Washington (and Downtown). A Blue Line Train can be seen in the background.
Those ARE the Gold Line LRV’s in the Expo test trains–the Gold Line trains are now almost entirely Breda units (700-class) now. We are approaching the 7th anniversary of the first Siemens LRV (238) arriving on the Gold Line to start track testing in August 2002. My wife and I and two friends stayed up until 3 AM to watch the unloading in South Pasadena.
