SeattleRailFan's video: Northbound freight train in Tukwila WA 3-26-2015

We had a nice sunny spring day here in the Pacific NW and I'm in Tukwila, about 15 miles south of Seattle. Listening to my scanner, I heard a train was coming northbound. I crossed over to the west side of the tracks to get the afternoon sun at my back. BNSF 5303 (C44-9W) came into sight leaning into the curve, bringing a manifest freight under the I-405 overpass headed for Seattle. The 2nd loco was a UP unit. For those may be wondering, the track directly in front of me is the UP Main. As the camera pans you can see some of the infrastructure that railroad use - signals on their masts, signal bungalow, station sign "CP Tukwila". The gray boxes to the right of the signal bungalow is an AEI (Automatic Equipment Identification) reader. It reads RFID tags on railcars to help the railroad know exactly where railcars are in their system. 5303 / UP 5306 / 4075 C44-9W / AC45CCTE / C44-9W
