Kevin Morgan, who runs ColoradoRailfan.com, was out photographing some rare power and unique sidings when he heard Amtrak's California Zephyr on his scanner. This particular train was detoured off the normal Burlington Route rails because a barge rammed a bridge in Iowa. Kevin caught up with the CZ at Leyden, already nine hours late.
It seems this train made it as far as Reno, Nevada, before it was turned around and sent back to Chicago because it was over 12 hours late due to the detour and traffic delays. Whether it's in or out of service on it's return is not known. Because the train was not provisioned at Emeryville, California, stocks on board the dining car will likely be near empty for the return trip. If it is running as number 6, I imagine it's probably going to be making a Harvey House stop (or three) on the way back.
