With the first phase of the Expo Line under construction between downtown L.A. and Culver City, Metro had been exploring naming the line after a color — as is the case with Metro’s rail and express bus lines. We even polled Source readers in April and 49.5 percent backed the Aqua Line with 18 percent behind the runner-up, the Bronze line.
Aqua does make sense, as the terminus for the second phase of the Expo Line will be near the ocean in Santa Monica.
Now, according to Curbed LA, Metro officials are saying the color issue has for now been settled: The name of the line will remain the Expo Line — as it has been called for years during the planning and construction process — but it will be colored aqua on Metro maps.
Of course, all of this could change a few years down the road. When the regional connector opens, the Expo, Blue and Gold lines will be connected in downtown L.A. and the plan is for the lines to share trains — i.e. trains will be running between Pasadena and the San Gabriel Valley and between Santa Monica and East L.A. (Here’s map of how that will work). At that point, Metro officials have said it may make more sense to rename the lines to avoid passenger confusion over the destination of their trains.
