A
Refrigerator Car ("Reefer") is defined as a fully enclosed
freight car used for carrying perishable commodities requiring
it to keep the commodities a constant temperature (usually cold
or frozen) during transport.
The Western
Pacific Railroad Museum features one of the most complete
collections of refrigerator cars of any museum in the country.
WPRM's reefer collection includes cars spanning the entire
evolution of refrigerated rail transport, from cars among the
first wooden reefers using large blocks of ice to cool the load,
to a very early example of diesel powered mechanical
refrigerator units, to modern cryogenic reefers utilizing carbon
dioxide to keep the load cool.
