I'm arriving in Union Station this week and will need to find the Metro Rail Red Line stop at the terminal vicinity. Unless I've just missed it, I don't find a map that shows where that is. I don't have a problem with just asking for directions when I get there but you'd think that information would be on line. It would be nice to know ahead of time. Any thoughts or helpful information? I'm taking a trip that involves a 230 mi truck trip, shuttle to bus stop, bus to Amtrak, Amtrak to bus with two changes and car to destination!!! I'd like as much information as possible. Are there clear signs that direct the way?
