The BEST Amtrak K5LA HORN I've Heard In Months??? Amtrak Train 91 Silver Star By Boynton 1-24-24

In this video, we first see southbound Amtrak train P091-23, the Silver Star at Boynton Canal. The lead unit had a particularly pleasant sounding 90s style K5LA horn - a sound that was more common decades ago. Next, at the same spot, we see a southbound Tri-Rail.
