In April, 3751 has a fire in her belly for the first time in 2016 as she steams to Los Angeles Union Station to be on display as part of the 2016 California Passenger Rail Summit. The following month, the engine takes part in the annual Fullerton Railroad Days celebration. During the last evening of the event, the SBRHS holds its first ever closed, professional night photography session. In July, 3751 finds herself at Los Angeles Union Station once again now on display as part of Metrolink’s unveiling of the new F125, Tier 4 complaint locomotive. With the success of this outing, Metrolink next requests 3751 to travel to Acton, Calif. – located deep in the heart of Soledad Canyon. Under the cover of darkness on September 27, 3751 becomes the first mainline steam locomotive to traverse the rails between Los Angeles and Burbank in 24 years and the first to traverse the rails between Burbank and Acton in 32 years. In mid-December, the locomotive makes its final steam up for the year as it attends the Trainfest and Toy Drive at Los Angeles Union Station hosted by LOSSAN and the Pacific Surfliner.
