I am keeping track of the arrival times for the CZ in anticipation of my trip. I need the CZ 5 for SAC and CZ 6 for CHI. Amtrak.com seems to be the most current but you must enter info every time. I would like to just click on a single link for each train. SAC Status and CHI Status seam to be the best but may not always be up to date. Have you found a better way to obtain the info? How do websites access the data directly from Amtrak.
