I confess, I've been coming to the Tehachapi area to chase trains for 50 years. OK, 49 but in 2014 it will be 50. "Back in the day" you could drive right up to the tracks but now the Loop property is completely gated off. Repeat visitors take note. Now you must drive up to the Loop overlook where the historic markers are and be satisfied with the overview. Be patient. Trains run when they are ready but I can tell you Fridays, Saturdays and early morning and evening are the best time to catch a train on the Loop. These days most trains loop around themselves which is quite a thrill to the first-time visitor. There is nothing at the site so use the rest room and take water before you head out. It's well marked and about 15 minutes off highway 58 at the Keene exit.
