Three trains in Tukwila, WA, 9-2-2015

Today I'm in Tukwila, WA, just south of Seattle to catch three trains in quick secession.
First up is a northbound manifest freight, pulled by a trio of Dash-9 locos, led by BNSF 5258 (C44-9W).
Next up was a southbound loaded garbage train, pulled by two GEVO C4's, led by BNSF 6907 (ES44C4).
The C4 locos have 6 axles but only 4 have traction motors. They cost less to buy, and are used on relatively light trains where you don't need the extra tractive effort given by having 6 traction motors.
Last up was a northbound loaded oil train, led by BNSF 6907 (ES44C4). The engineer was giving lot of whistle and bell for a work crew just out of sight. They're involved in the adding of a third main track in this area.
Freight:
5258 / 4976 / 4329
C44-9W / C44-9W / C44-9W
Garbage:
6907 / 6834
ES44C4 / ES44C4
Oil:
7242 / 701 / 6542 / 7102
ES44DC / C44-9W / ES44C4 / ES44C4

They're going to add a third BNSF mainline to the Seattle Sub? Traffic must really be picking up! How would they fit a third track in through all of the railroad crossings and Sounder sations?

+jpfrench325 Yes, they're in the process now.
BNSF got the money for the 3rd main from Sound Transit. BNSF must give Sounder trains priority over all freight, they must meet strict on-time standards. So right now, between Seattle and Tacoma during rush hour BNSF gives one main over to Sounder leaving only one track for freight. With a 3rd main between Seattle and Tacoma, BNSF can use two track for freight, making it easier to run freight north and sound during rush hour.
The 3rd main is done from King Street Station to somewhere around south of Boeing Field. They are starting in on the next segment now. Work is going on around Tukwila, then I think they'll work they're way down to Auburn.
