From the Streetcar to Union Station is completely unintuitive:I wonder if you could expand on this. From my map reading, it seems like the end of the Streetcar route is Union Station, not inside but at the intersection of H Street and Capitol Street, which google maps says is a 9 minute (1/2 mile) walk from the exit of Union Station. Once aboard the Streetcar, your ride to the H Street Coridor would be direct and take a couple of minutes.
The end of the streetcar is in the middle of a busy street with fencing everywhere. To enter Union Station from the streetcar, you have to get from the streetcar in the middle of a street to a parking garage on the other side:
There is nothing about the parking garage that indicates it serves as the entrance to a train station. The signage indicates "PARK," "Buses," "Rental Car Returns," etc., but has no mention of Union Station.
You then have to walk through a parking lot of buses until you get to the main bus terminal area, from which there is another set of corridors that take you to the train station.
Going the other way is unintuitive as well:
From the train boarding area, if you want to get to H Street/Streetcar, you don't follow the normal exit signs. Instead, you have to follow the sign "Buses, Parking Garage, Car Rental," which makes no mention of an H Street exit or streetcar service:
It is only once you are nearly to the bus terminal that you see any mention of the streetcar:
And you still have to walk through an unattractive corridor, through an unattractive parking garage, down a busy street, and to the fenced-in median of the busy street to wait for the streetcar.
