Metro’s Blue Line Becomes the A Line with the Completion of New Blue Improvement Project

Monday November 04, 2019

With the completion of the New Blue Improvement Project, Metro’s new rail and bus rapid transit line renaming convention will go into effect with Metro’s Blue line now being referred to as the A Line. This begins a three-year process to rename all Metro Rail and Bus Rapid Transit lines by 2022.

Under the new system, each Metro Rail and Bus Rapid Transit line will be designated by a letter and color. The Metro Board of Directors approved a new line naming convention in November 2018, citing the need for more consistency as the Metro system grows.

The new naming convention helps alleviate several issues. In the past, most Metro Rail lines were named after colors with the exception of the Expo Line and the Crenshaw/LAX Line that are named after street names and places — which riders may find confusing. Metro’s system map has also been reliant on colors and can be difficult to read for those who are color blind. Adding letters will help avoid this problem.

“It is important that we have one consistent systemwide naming convention that is simple, easy to read, and use,” said Metro Board Chair and Inglewood Mayor James T. Butts. “Letters combined with colors will make it clearer to residents and visitors who use our system.”

Starting with the A Line, the majority of station signage will simply show the letter A within a colored dot. The rest of Metro Rail and the Silver Line and Orange Line will transition to the new naming convention when the Crenshaw/LAX line opens. The Crenshaw/LAX Line currently does not have a letter name as Metro’s operation staff is still working on finalizing the line’s operational plan.

“We believe this is great news for the region because we have big plans for new rail and bus rapid transit lines in the years to come,” said Metro CEO Phillip A. Washington. “This new naming convention will help keep our system easy to navigate and make it more user friendly — and, thus, improve the customer experience.”

Under the new naming convention, the Red Line will eventually become the B Line, the Green Line will be the C Line, the Purple Line the D Line and the Expo Line the E Line, to name a few examples. The Gold Line will become the J Line until the Regional Connector opens and ties together the Blue, Expo and Gold Lines. The eventual Azusa to Long Beach line created by the Connector will be known as the A Line while the East Los Angeles to Santa Monica line will be the E Line.
