On the trip back home on Amtrak, there was a terrorism scare in Utah that turned out to be nothing more than an Amtrak engineer blowing by a red block signal. All Amtrak long distance trains were shunted onto the nearest siding until the mess in Utah was straightened out. We spent five hours on a siding on the Union Pacific route in the mountains near Dunsmuir (CA) going nowhere.
Ugh. What “fun” that must have been! I’m glad it was not a real threat however. I can remember that when the rail system was down, the country was down.
