In Arcadia, a steel railroad bridge transitioned the Atchison, Topeka and Santa Fe Railway between the I-210 and street grade.[6][7] Arcadia train station was added two years after the original the Los Angeles and San Gabriel Valley Railroad opened in 1885.The passenger station was decommissioned in 1951 and relocated in 1970 to the Fairplex, RailGiants Train Museum that is located inside the Los Angeles County Fairgrounds in Pomona.The Santa Fe line served the San Gabriel Valley until 1994, when the 1994 Northridge earthquake weakened the bridge in Arcadia.[citation needed] For an unknown period of time, the station was the home of a private railcar called the Pine Bluff until its purchase in the mid-2000s.
