Hitting the curve at the west end of the Metrolink Buena Park station is Amtrak Pacific Surfliner 775, making the 350-mile (5729-km) trek from San Diego to San Luis Obispo. And, thanks to very slow speeds (due to Union Pacific's poorly maintained trackage, this trains speed averages just 43? miles per hour on the final 109-miles [175.5-km]), this trip only takes 8?-hours! Amtrak cab/baggage/coach 6905 is leading this train, with F59PHI 461 is shoving on the rear, but from Los Angeles to SLO, the F59PHI will be leading this train.
