Hello how may I help you? Can you tell me how to get from the Tacoma Dome to the airport? Yes all you have to do is catch bus 18162 downtown and then catch the train from there Which train do I take? Southbound train to 69th Street And how long is this whole trip? I need to know how early to start. The whole trip takes approximately two hours OK. Do both the bus and the train run on Sundays? Yes they both do run on Sundays but on a delayed schedule How delayed? They usually run every 15 minutes now it's every half an hour
