Question on today's Zephyr into Chicago

[Chief]

I'm getting ready for my first trip from Osceola, IA to Naperville, IL. I've been tracking the timeliness of recent days so I can have an idea of what to expect for my trip. It looks like the train didn't even make it past Salt Lake City today. If this is so, would anyone know why?

Apparently a glitch in the system. Today, it looks like the Chief arrived 20 minutes early on Tuesday.
