Several GGW editors and contributors are in Seattle this week for the Railvolution conference. While there, they’ll offer a series of short posts about their experiences.

Seattle has a lot of interesting transportation infrastructure. Among the most interesting is the Seattle Transit Tunnel, a 5-station subway that forms the core of the city’s transit network.

It started off as a bus-only subway, but became a joint bus/rail tunnel when Seattle’s Central Link light rail line opened in 2009.  Each station is different, but one, Pioneer Square, would look particularly at home in DC:
