The fuselages are mounted to their 89' carriers at three points corresponding to the eventual locations of the landing gear struts....Before loading, all openings such as cabin doors, access pannels and the like are sealed with special yellow tape to prevent moisture from getting into the sensitive componenets and causing corrosion en route. The larger openings such as wing spars are covered with clear plastic inserts designed to fit in each location. Each model of the 737 requires a different set of inserts and each insert is seperatly numbered for tracking....According to a source at Boeing, they receive usually one train with three fuselage sections a week from Wichita. [NWownRailfan]Behind every flatcar carrying a fuselage is an idler flatcar. I see that in the photo above a box carrying a cockpit for a 747 is on the idler car. [Trains] In this case (source), the idler car is empty and a couple of Boeing workers are riding on it. In this case, every idler car has a cockpit box.
BNSF is making more special cars because Boeing is ramping up the production of 737s. [BizJournals] In a different article, I read they intend to build 47 a month by the end of 2017.
Boeing declined comment on how dumping a few fuselages into a river would impact their production.

(new window) The guy taking the video never turns back so that we can't see how much the ears that were cut into the Cascade Tunnel (7.8 miles, the longest train tunnel in the US) clears the double stacks. The square top of the containers is the reason those "ears" were cut. Other tall cars such as autorack cars have curved upper edges so they don't need the "ears" in the tunnels.
For the 787-9 Dreamliner, even more sub-assemblies were made at other locations. The timelapse video below shows how they are assembled. Final assembly plants are located in Washington and South Carolina. I remember reading articles about the production of the first planes being delayed because they had serious supply chain problems to work out. Now we can read retrospective articles about those problems, e.g. Forbes. Delivery was pushed back seven times for a total delay of three years. The cost overrun was billions of dollars because Boeing ended up having to send its engineers to the subcontractors to help solve the problems. And they had to compensate their successful subcontractors for profits they lost due to the delay in production, which delayed the revenue stream.
I think the assembly plant was a greenfield plant that Rockford, IL bid on. Obviously, they lost. Boeing ended up with a location in South Carolina because the subcontractor there, Vought, was so missed up that they ended up buying the company to fix it. [Forbes]
