Sound Transit enters pre-revenue phase

Sound Transit has entered the pre-revenue phase on the East Link light-rail extension project. The phase includes training for operators and maintenance staff and continued testing to ensure stations, tracks, utilities and vehicles work together as expected in preparation for the start of service in spring 2024. 

 

According to Sound Transit, in addition to trains on the tracks, people in the area can expect to see maintenance vehicles, testing equipment and personnel involved in the testing process and hear sounds typical in an operating light-rail system, including station announcements, wheels on the tracks and warning signals. 

 

The next phase of testing will be simulated service, expected to begin in early 2024.
