Daggett to Barstow is four track and is probably the most heavily traveled railroad in California. It is both UP and BNSF. It is parallel by a good unpaved road. I would skip Victorville and then follow the tracks from Hesperia to Cajon Junction on State route 138. There are a number of side roads to the north that will take you to the tracks. All are unpaved, but are good to drive on unless it has been raining. In this area sabotage of the Santa Fe that caused a serious derailment has made the railroad sensitive to trespassers. Stay off railroad property. West of Summit tracks are mostly in national forest land so public assess is acceptable. At Cajon Junction there is gas and several places to eat. To continue following the train will require getting on I-15 south. Get off at the next off ramp and follow old Route 66. There is one paved road to the west that goes to and crosses both BNSF and UP, but it will probably be jammed. There is a good view of both railroads across a canyon and creek from Route 66 and lots of parking. No way of knowing which railroad 4014 will be on, UP uses both (former SP and ATSF). At the bottom of the hill old Route 66 reconnects with I-15 and I-215. This is rattlesnake country. Watch were you walk and stay out of brush and loose rocks.
