Definitely worth the trip. Saw 4 super long trains in the hour we were there. Highly recommend stopping at the RR museum at the old station in down town Tehachapi. They advised that Monday has the least train traffic as that's the designated minor maintenance day. Also there's a great "local Color" train store across the street that has a wealth of info on the local area. We stayed in our motor home at the Kmart ( use the SW corner away from the store ). a good info site on the loop is >>>
Two YouTube Videos I posted on this loop are: >>>>
