In late September of 2016, the SBRHS is approached by Metrolink to have 3751 participate in the grand opening ceremony of a new station platform at the Acton/Vincent Grade depot, 60 miles north of Los Angeles. Making the run under the cover of darkness from Los Angeles Union Station on the evening of September 27, 3751 becomes the first mainline steam locomotive to operate north of Los Angeles in 24 years – the last being the “Earth Train” pulled by the ex-Southern Pacific 4-6-2, No. 2472 in 1992. Banking to the east at Burbank Junction, 3751 becomes the first mainline steam locomotive to operate on this line that travels up through the ex-Southern Pacific Soledad Canyon line in 32 years – the last being ex-Southern Pacific No. 4449 as it lead a train south on its journey to New Orleans for the Worlds Fair in 1984. Following the ceremony on the morning of September 28, the locomotive is towed backwards home to Los Angeles by two escorting BNSF AC4400CW’s on lease to Metrolink.
