Mine was over 12 hours late, as a passenger had to be airlifted off because of cardiac issues. Said passenger had been told not to fly, because of altitude issues, and hadn´t thought through the "mile high" aspect of transiting through Denver.

It is one of the most amazing train trips in the world, and tbh the article doesn´t really do it justice. The day the train spends slowly going up and down the rockies, are just incredible, the scenery is amazing, and you get to know other passengers and the conductors along the way. Had some great card games in the scenery car.
