Okay Guys, I will answer all of your questions about the Boeing job, and why the turntable is up at the plant…
Boeing ships to both the Everett Plant and the Renton Plant via rail, and I’ve worked both jobs. The Renton plant is much simpler and simply gets 737 bodies from the plant in KC. The 737’s normally travel up to the MRL, then over Steven’s, into Seattle, where a local works the Renton plant. BNSF has on time delivery schedules for both plants and will order special J trains just for Boeing cars if its need. BNSF will also order extra locals/switcher to spot both plants if needed (and be willing to make a good pay day for the crews)…
Now, with that background I can tell you about how the Everett plant works. First of the Everett plant gets widebody containers (22’ wide & 16’ wide both about 16-18’ tall) off ships, some 747 parts via train (16’ wide loads), and assorted other junk. The grade up to the plant is 5.7% from water. To work the job, you change the brake pipe pressure from 90 psi to 110 psi, and use two specially equipped locomotives with extended dynamic brakes. The engines always stay on the downhill side of the train. Up until a few years ago, the Boeing job would start at Everett Yard, and work their way to the Port, to pick up the 22’ wide containers, and any thing else at the “Mile Post”. Then through a fancy number of crossovers between main 1 and 2, you reach the Boeing Spur. When Boeing started talking about building the Dreamliner, they convinced the State of WA to build them a direct access slip at the base of the Boeing Spur with the intention that 787 parts would come via boat & train. That’s what you see in the Google Earth view. After you gather all the cars up and make an air test, you shove up the Boeing Hill. About 1/2 way up is a split point derail that allows you to run through it uphill (stop on the downhill). Once you reach the plant, you have the 8 or 9 tracks to work. The turntable doesn’t get used too much, but if something needs to be spun for spotting purposes that’s where the magic happens. Before you cut away from the locomotives, each car gets a tight handbrake, a wheel chock, and a full set of air. All though the spot tracks are somewhat ‘flat’ they still have a slight downhill grade.
I’ll see if I can find some pics online and link them.
