Introduced in 1988, the All-Purpose Spine Car is an outgrowth of several
earlier designs.
Many of the principles were introduced on the Fuel-Foilers, developed by
the Santa Fe in the mid 1970s for trailer service. These cars were built
around a center-beam frame, (known today as a spine) fitted with a trailer
hitch and platform for the wheels. The articulated design eliminated
couplers between units, reducing slack action and load damage.
Trailer Train began a series of design experiments along similar lines,
introducing its Four-Runner in 1981. Consisting of four drawbar-connected
units, these cars could haul trailers from 40 to 45' in length. This
lightweight design was not overly popular, but it paved the way for a
stand-alone version, called the Front Runner, which could handle the newer
48' vans then coming into service.
By 1986, larger containers and double-stack cars were becoming standard
equipment for intermodal service. But many railroads had low clearances or
insufficient container traffic that made double-stack cars impractical.
These lines needed a lightweight, articulated car and Trailer Train
responded with the Spine Car. Each consisted of five units, set up to carry
a single stack of containers ranging from 20 to 48' long.
Working with the railroads to determine their changing requirements,
Trailer Train introduced the All-Purpose Spine Car in 1988. Equipped to
carry containers and trailers at the same time, each of the five units in
the car is fitted with collapsible hitches and container locks. Trailers
from 28 to 48' long, or 40, 45 or 48' containers can be carried. The end
(A&B) units have additional locks to carry a pair of 20' containers. Brake
wheels are installed on each end unit, reducing the rigging to activate the
hand brakes.
Today, these all-purpose cars can be seen running in general freights, or
with other types of intermodal equipment.
