Planes on a Train

Yesterday while waiting for the bus to Magnolia along Elliot Ave, a train carrying three Boeing 737 fuselages went by. Presumably heading south to Boeing Field from the Everett plant?

EDIT: Correction from my uncle and dad: these fuselages were probably built at Wichita, KS Spirit AeroSystems plant and are heading for the Renton Boeing plant.

Two unpainted green 737 fuselages are visible through trees in front of the water of Elliott Bay across a wide street. They are pointed left as the train rolls southbound.An animated GIF of a burst photo showing cars zipping by both directions in the foreground while three plane fuselages on a train slowly move to the left in the background.
