The instant invention relates to improvements
in refrigerator cars, and, more particularly, to
an improved drip pan construction for cars of this
type and to a combined drip pan and ?oor con
sheathing overlying the insulation l0 at the end
struction.
A principal object of the invention is the pro
vision of a drip pan constructed of a ?exible, non
metallic, waterproof material, particularly for
of the car, and a tongue and groove wooden ?oor
ing [6 extending across the width of the car over
lying insulation l2 and supported on suitable
sills (not shown). Flooring I6 is continued to a
bearing rail 18 for the bulkhead separating the
ice compartment from the lading compartment.
Between bearing rail l8 and the end of the
car, space is provided for the drip pan which
use in refrigerator cars provided with ?exible ?oor ‘
coverings. Heretofore, in the building of refrig 10 may be supported on a sub-?ooring 22, compris-'

employed including those comprising one or more
