In 1888 the Ontario & San Antonio Heights Railroad Co. laid tracks in the center of Euclid Avenue from California Street to the San Antonio Heights, where a team of mules pulled the trolley uphill and rode down the hill in a trailer. By 1895 the Ontario Electric Company had organized and begun converting the trolleys to electricity. Sometime before 1902 William G. Kerckhoff purchased the troubled Ontario Electric Company, and in 1906 his company bought a large parcel of land to subdivide for houses, including a park to which trolley service was to be extended. This fieldstone waiting station was offered as a convenience to trolley patrons. In 1911 the rail trolley company extended service to Claremont and Pomona from Ontario and Upland on an hourly schedule until 11 p.m. On March 19, 1912, the Pacific Electric Co. purchased the O. & S.H. Railroad Company. The 15 acre park was transferred to the City of Upland in February 1925 for a consideration of one dollar. The mural inside represents the many accomplishments of William G. Kerckhoff; he never failed and his word was his bond.
