Systems Testing

Testing of the Green Line Extension began in July 2025 and will continue until the line opens in 2027. Over 4,000 tests will cover the different components of the LRT operating systems. Some of the tests that will be most visible to the public will involve the LRT grade crossing warning device (gate crossing arms, flashers, etc.) and signals systems, verifying the track alignment, and testing the power delivery to the trains.  

Testing is essential for ensuring the safety, reliability, and efficiency of the light rail system before passenger service begins in 2027.

Staying safe during systems testing

Trains are moving along the tracks and warning systems are now active. Know the following safety rules and share them with others:

• Never try to beat a train; it can’t stop quickly. Wait the minute it takes for the train to go by.
• If you see flashing lights, stop. Trains can come from either direction at any time.
• Bells mean a train is coming. Don’t wear headphones or text near tracks. Eyes up and ears open!
• Tracks are for trains only. Never walk, bike, or play on railroad tracks. Marked crossings are the only safe places to cross.
