California State Parks and the California State Railroad Museum are gearing up to celebrate “Diesels and Dads” on Father’s Day weekend – June 20 & 21, 2015 -- by operating two visually-exciting and gracefully-styled diesel locomotives as part of the popular weekend excursion train rides on the Sacramento Southern Railroad. Departing hourly from 11 a.m. to 4 p.m., the brightly painted diesels -- Western Pacific No. 913 and Southern Pacific “Daylight” No. 6051 -- will pull the excursion trains both Saturday and Sunday on Father’s Day weekend. The eye-catching and classic streamlined locomotives are representative of the so-called “First Generation” of diesel-electric locomotives which replaced steam engines all across America during the 1940s and 1950s.
