The Cajon Pass
Follow the BNSF Cajon sub and the Union Pacific Mojave sub up the Cajon Pass in real scale. The map starts at Control Point Baseline (M.P. 79.8) and ends at Control Point Summit (M.P. 55.9). The Cajon is located in San Bernardino County, California, about halfway in between L.A. and Las Vegas. The pass sees several dozen trains per day. (Two Amtrak, a dozen or so UP, and several dozen BNSF trains.) This mountain pass housed Route 66 and much of the original 66 is still visible today. However, the I-15 now is the main road many take through the pass. This map is about 24 miles long in real life measurement and all tracks are exactly 1:1. Due to this, it will take a minute or two to load the map but be patient.
Note: This map is very large and requires a somewhat high-end PC to run.
