I’ve arrived at union station around this time and later. Some homeless people accost travelers immediately as they leave the building, one woman got in my face and called me a bitch. But it’s overall fine. Just don’t make eye contact and keep walking.

Best bet is to take a taxi as there are usually a bunch waiting and the Uber area is backed up/expensive. I wish they would station a police officer in this area to act as a buffer. But still, I don’t really consider this area dangerous. There are usually plenty of people outside waiting.
