Mukilteo is a Sounder infill station that opened on May 31, 2008. When I visited in 2011, the current platform felt very temporary and is designed to be. It consists of a single platform on the Pudget Sound side of the tracks with a tactile warning strip, a line of green lampposts and a few benches inside brown bus shelters with plastic roofs. There is a single shelter with a few TVMs of the same design. There is also an abstract concrete sculpture on the platform.
A fence separates the track that platforms from the two mainline tracks. This platform area leads south to and ends at an access road where there is a single turnaround loop. Along this road is the stations only 63 parking spaces. A walkway continues following this access road along the tracks and leads to a few seaside shops by the water and the ferry terminal for the Washington State Ferry to Clinton on Whidbey Island. Passengers accessing the station have to dodge the vehicle line-up area for the ferry as well, and then can finally get to WA-525, the Mukilteo Speedway, and the one vehicle bridge across the railroad tracks, uphill to the town center of Mukilteo.
In 2020 a new perminant Mukilteo Station opened. This station has two platforms with a pedestrian bridge (with elevators) connecting them and more perminant shelter structures.
