I would like to leave Chicago 10/30 on the EB arriving Portland at 10:10 on 11/1 then catch the CS at 2:25 pm arriving at SAC at 6:15 on 11/2 the the CZ at 11:09 back to CHI. Is this doable or am I being too ambitious? My main concern is being able to catch the CS if the EB is late. I do not want to end up riding coach on an LD train back to CHI. Too old for that anymore
