LA, meet your line letters.
Metro has updated rail and busway line names. We’ve added a letter to help our riders choose their journey.
Metro is growing.
That’s great news for LA, because we have big plans for new rail and busway lines. As we add new service, we’re updating our names so it’s easier for everyone, including riders with visual impairments, to get where they need to go. So what’s new? We added letters to the color and symbol for rail and busway lines.
Look for line letter signs.
You will see the addition of letters to line colors on station signage, maps, timetables, posters, our website, other digital platforms and everywhere else you find our colored dots and squares.









New downtown LA stations and the K Line
Coming soon, three new underground stations will open in downtown LA as the Regional Connector Transit Project finishes up. These stations will open for service with new line letter signage.
The K Line opened for service in 2022, with seven stations featuring K Line signage.
It takes time to update everywhere.
Our plan is for all stations to have updated signs in the next several years. We promise to make the transition as smooth as possible, but you will likely see both old and new for a little while as we make the change. The line colors currently in use will remain the same.
A temporary naming system
During the transition, a hybrid naming system will use both the letter and the color to refer to the line. For example: the Blue Line becomes A Line (Blue). This hybrid system will be phased out eventually, and then we will only use the letter names everywhere on Metro. For example, the A Line (Blue) will be referred to simply as the A Line.
Fares, routes and schedules are not changing as a result of this name update.
Thanks for going Metro as we grow.

FAQs
Why did Metro add letters to the current naming convention for rail lines and busway lines?
We updated line names to include a letter to help everyone, including riders with visual impairments, plan a better journey. Customer feedback, research and testing revealed that the addition of letters to our colors are easier for everyone to understand than color alone.
What is new?
The addition of letters to line colors will appear on station signage, maps, timetables, posters, digital platforms and everywhere else you find our colored dots and squares. The colors did not change, and we will continue to use them as we do now to indicate routes and service.
When is this update happening?
We’ve made the transition to the A Line (Blue), so there’s new signage on the A Line. The E Line (Expo) already uses line letter signage. And the new K Line opened in fall 2022, using the new naming convention. Updates for the rest of our rail lines will follow.
Our goal is for all Metro Rail and busway stations to have updated line letter name signage within the next few years.
On digital platforms such as our website, apps and digital kiosks, you’ll start seeing changes sooner. Printed material will be updated as the opportunity arises, and we will prioritize timetables, maps, posters and fact sheets in order to keep riders informed.
How were the letters chosen for the line names?
Letters are assigned in the order of each line’s original opening date. For instance, since the Blue Line was Metro’s first rail line to open in 1990, it became the A Line. All current and future lines will get the next letter in the alphabet based on its opening date.
