Amtrak’s No. 3, the Southwest Chief, slams over the east switch at Simpson, Colorado, on February 26, 1999. Trailing the three GE P42DCs is a baggage car, eight Superliners, a former F40PH rebuilt (cab-bagage car) being sent west to Los Angeles, seven Express boxcars, two MHCs (Material Handling Cars), and lastly, on the rear are three Roadrailers. The 21-car train is making good time, as the slowly-lowering semaphore adjoining the second Superliner suggests!
Two Amtrak routes serve the Centennial State. The California Zephyr's route through Moffat Tunnel and along the Colorado River goes from one end of the state to the other. The Southwest Chief cuts across the southeast corner.
