Close to 2:00 in the morning we were approaching San Antonio. We went through a large exchange yard on the outskirts, and then came to a stop in the station along several sets of parallel tracks where we jockeyed to add two cars to the train.
We sat idle for a while alongside another train that appeared empty. Apparently, it was the Sunset Limited eastbound. The attendants intermittently bustled through the car, checking the destinations of everyone to make sure to wake those who were disembarking.
A lone stumbling Mexican repeatedly strode up and down the aisle looking as if on an urgent errand never to be fulfilled. I later found him asleep in the sightseeing car. He must have been looking for a place to crash.
We stayed parked in the station for several hours, our car immediately adjacent to a massive, throbbing engine idling. Once a rail worker in overalls and a hard hat passed through the car. The low frequency so nearby and loud became somewhat oppressive.
I finally curled up across two seats and got some sleep. It seems we got moving about 5:30. I briefly stirred but then woke again at almost 8:00 as the signs of civilization were waning.
I went to the obsevation car, obtained some ice for my Dr Pepper, and had my breakfast there. I overheard one passenger comment that she woke up and thought she was in Africa.
