trackage to a new terminus at the San Bernardino Transit Center. The project's groundbreaking was in February 2014; at that time, the extension was expected to be completed by mid-2016. , the completion date had been extended to 2017. Construction work on the extension continued through March and April 2017. Test trains began running on the tracks in April 2017. This phase of the project opened to the public on December 16, 2017. Arrow is a rail extension to Redlands. By December 2015, SANBAG decided that this second phase of the project, from the San Bernardino Transit Center to Redlands, would no longer be a Metrolink extension, but rather an independent system. SANBAG planned to use diesel multiple units (DMUs) and have Omnitrans operate the system. However, San Bernardino Line express limited-stop trains would run on part of the extension, to a new station near the Downtown Redlands station. Construction was planned to begin in 2017, however groundbreaking took place in July 2019 with a 2022 opening. The selected route runs between the Downtown San Bernardino station and the University of Redlands with stops at Tippecanoe Avenue, Esri, and Downtown Redlands, adjacent to the Redlands Santa Fe Depot. Omnitrans was removed as the system's operator in 2019 amid mounting deficits, and Metrolink took over construction and procurement. Arrow opened on October 24, 2022. Arrow's DMU sets have been studied for wider deployment on the rest of the San Bernardino Line. The rolling stock is the new EMD F125, and others were MPI MPXpress, EMD F59PH, and some cab cars. Stations The San Bernardino Line has 15 stations, plus two events-only stations. Express trains only serve seven of the busiest stations on the line.
