Michigan services are a mess. (Yes, the weather situation in Chicago affected many services, but I was focusing my attention on the Wolverines and the Blue Water). I wonder how many passengers hung around for last night's 354. In the advisory for the selective cancellations ahead of time, the morning and evening departures in both directions were listed as operating Dec 22-25, with only 352/353 canceled. Seems like if the temperatures were the issue, the midday trains would have a better choice of operating than early morning or late night. Today it appears that all the Wolverines are cancelled but 364 is expected to depart (do they use that same delayed equipment?) Amtrak Alerts, cannot sugarcoat this, was doing a poor job of providing updates last night and into the wee hours. This morning the app shows 350 and 351 now cancelled, but the Alerts stated a few minutes ago that 350 was delayed and updates to come. I'm sure the delays also caused crew issues but holy cow this is bad. And across the border, VIA RAIL corridors to Toronto are operating, albeit some late.
