hances are high, if
you have flown in
the past few de-
cades, that you
have ridden on a
Boeing 737 air-
craft. Assembled
in Renton, Wash.,
outside of Seattle, one may not
know of the unique path the
aircraft has taken to get it to
cruising altitude so you could
lower your tray table and
recline your seatback.
People may not believe you
when you tell them that the air-
craft that you are in made its
path to flight from the rolling
prairies of Kansas, through theSand Hills of Nebraska, across
the Rocky Mountains, along
stretches of mountain rivers
and then over the Cascade
Mountains, including through
8-mile-long Cascade Tunnel.
The production of Boeing
aircraft and its partnership with
the railroads as part of its sup-
ply chain has been in place for
several decades. Components
and partial airframes for the
aircraft have ridden the rails
from Kansas, Texas, and Cali-
fornia since the 1960s.
Beginning in July 1997 with
the first 737-800 Next Genera-
tion aircraft, Boeing has been
moving full 737 fuselageframes, along with wing assem-
blies and other components,
from Spirit Aerosystems of
Wichita, Kan., via BNSF Rail-
way and Montana Rail Link to
its assembly locations 2,200 rail
miles away in Everett and Rent-
on, Wash. (Deliveries to Everett
include components for the
construction of 747, 767, and
777 aircraft assembled there.)
Prior to 2019, when soft-
ware problems forced the
grounding of the 737MAX
fleet and slowed production of
new planes, the railroad was
moving up to 52 airframes
each month, and Boeing plans
to increase those numbers in
the future. In February 2018,
the 10,000th 737 fuselage
arrived at the 1.1 million-
square-foot Renton assembly
plant (see page 32).
Trains carrying aircraft
frames require special handling
and care due to its size and
need to ensure that no damage
occurs to the lading. Evenminor damage can result in the
total loss of the fuselage due to
integrity issues. In 2014, a train
carrying six 737 fuselages de-
railed along the Clark Fork Riv-
er while operating over Mon-
tana Rail Link near Alberton,
Mont. The derailment resulted
in several fuselages ending up
in the river. Due to the severity
of the damage that occurred
during the derailment the fuse-
lages were scrapped nearby.
Although they can move in
a dedicated train, fuselages are
added to the head end of trains
out of the Midwest and can
then be swapped out for Seat-

imagine flying in the locomotive
instead? Charlie ConwayROUTE OF THE 737
