People tend to check in during these times:
To good transit...go there.
Train stop in St. Louis, catch a bite to eat if you have time...listen to the announcements and don't miss your next train out!
Alcohol is forbidden in the station, so don't get there too early thinking you'll find a bar. You'll be quite disappointed.
Interesting place, you see Greyhound passengers, Amtrak passengers, and guys who just got out of the "Work House" with their property boxes! People watching is a premium here.
Ask your conductor to make an extra loud announcement recommending people not remove their shoes.
The Metrolink station (light rail) is right outside the door. Very convenient.
Bring snacks there are 3 places to eat and all high calorie crap
This station is adjacent to the Civic Center Metrolink Station.
You're going to see some interesting things while here. Try not to let them know you're watching.
There's a deli, a Pizza Hut and a KFC.
Don't talk to strangers.
They start boarding 30-20 mins before departure time. It's a nice station now and it's indoors.
