After settling into the train about 3:30 AM, I tried to spend some time messaging Mandy but she fell asleep again in the middle of an exchange. Frustrating! The train started five hours late, and got later. By morning it was nine hours late -- we lost another five hours in six hours. By teatime it was 10 hours behind. Seems that there is only one line and we have to keep stopping to let freight trains through -- even having to back up occasionally. We found out later than Amtrak uses a freight line between New Orleans and Jacksonville, it has no priority over any freight train. Hence the slow progress.
