Track & Signals
Prepare for the multi-year, three-phase Track & Signals project for the entire METRO Blue Line. Stay ahead of what is coming in each phase, learn about replacement bus service, and discover the scope of the improvements coming to the Blue Line corridor.
The Track & Signals project is part of the Renew the Blue system restoration initiative and will help it remain a safe, reliable, and affordable transit option for many years to come!
Phase 1 of the Track & Signals project was completed in 2025.
Phase timeline and general work overview

2026: Phase 2
May - Aug.
Replacement Blue Line bus service will operate during these dates in 2026*:
- May 9 – 10: Buses replace trains between Target Field and Fort Snelling stations
- May 30 – 31: Buses replace trains between Target Field and Fort Snelling stations
- June 29 – Aug. 19: Buses replace trains between Target Field and Mall of America stations
The shared downtown Minneapolis METRO Green Line stations will also be affected during segments of the June 29 – Aug. 19 Blue Line maintenance period:
- June 29 – July 26: Buses replace Green Line trains between Target Field and West Bank stations
- Aug. 16 – 19: Buses replace Green Line trains between Target Field and West Bank stations
*Dates and affected stations are subject to change
Signal your intent!
Phase 2 contains a complete upgrade of the train signal equipment. Light rail trains are controlled by a complex system of signals. The original signal equipment is over 20 years old and is at the end of useful life.
What’s changing?
- A brand-new signal system for improved reliability.
- Enhanced ‘reverse running’ capability—keeping trains moving even in unusual situations like stalled trains or emergency track repairs.
- Smarter routing to keep schedules on track.
Most of the work will happen behind the scenes, inside signal houses along the tracks from Franklin Station to 42nd St. You may not always see the construction, but trust us—big improvements are in motion!
The work completed in Phase 2 will result in a new signal system and track configuration which will allow for more options to route trains efficiently, resulting in improved schedule reliability. A big win for us all!
2027: Phase 3
April - May
(53-day full closure)
May - June
(partial closure)
June - July
(partial closure)
Finishing touches!
Phase 3 work will be a continuation of the signal work that will have ended at 42nd St. in 2026. This work will now extend to Airport -Terminal 2. The rail system south of Terminal 2 was already upgraded over the last few years.
Phase 3 also includes major work in the Airport tunnel. This includes concrete work and full rail replacement.
The benefits of this third and final phase will improve the Blue Line in the ways mentioned in Phase 2, create a smoother ride between airport terminals, and extend the overall service life of your Blue Line.
