Sonoma-Marin Area Rail Transit recorded its highest ridership numbers last year since launching the rail service in 2017, officials reported. SMART, which operates 45 miles of passenger rail from Larkspur to Santa Rosa, stated it carried about 750,000 riders in 2023. That represents a 4.5% increase over the previous record high of 717,900 riders set during pre-pandemic conditions in 2019, said Eddy Cumins, general manager.
