I've boarded and detrained during the middle of the night at various locations. When I have boarded the southbound Crescent at Charlotte (2:45 AM), I spent the time downtown until soon after midnight, at which point I used public transportation to the station. Once there, I prepared as though I was going to sleep so that I could soon after I boarded the train. I did similar things when boarding the westbound Capitol Limited at Pittsburgh and a very late northbound Crescent at Atlanta. When boarding the southbound Crescent at Greensboro, I also explored the city although I returned earlier as there was no public transportation at that time of night and there was a limited number of things to do downtown. As far as detraining, I have had two experiences in the past year. In January, the southbound Silver Star I was aboard arrived Tampa nearly 12 hours late at just before midnight. Once all the bags were claimed, the building was promptly closed, but I was easily able to get an Uber to take me to my apartment in Clearwater. The other time was last November, when I arrived Salisbury, NC in the middle of the night on the northbound Crescent. I had to connect to Raleigh, and chose to book myself on the afternoon train rather than the morning train and transfer at Salisbury rather than Charlotte so that I could visit the North Carolina Transportation Museum. The Crescent was averaging several hours late at the time, so I was caught somewhat off guard when I arrived right on time at around 2:30 AM. The station attendant was friendly, but had to close the building, leaving me out in the 30 degree weather in the small town. I actually enjoyed the cold, but there was no activity in town until around 7 AM, with the exception of the 24 hour Waffle House about half a mile away. Just prior to sunrise, I ended up walking around downtown, where I stayed to watch the northbound Carolinian. I then walked the 3 miles to the museum and spent a few hours there before walking back to board the Piedmont. I loved the museum, but would prefer next time to make a day round trip on the Piedmont while visiting Raleigh rather than using the Crescent with its poor calling times. My experiences in big cities were fun and I had no safety issues, but I would definitely prefer to have visited them during the day. My experiences are also somewhat different in that they were all during transfers, with the exceptions of Atlanta and Tampa.
