What nickname was commonly given to the refrigerated rail cars introduced in the mid-19th century?
Answer
Reefers
The mid-19th century marked the beginning of mechanized cooling during transit, primarily associated with the expansion of railway systems moving goods across growing urban centers. The vehicles designed for this purpose, refrigerated rail cars, became commonly known by the colloquial term 'reefers.' These early reefers utilized ice packed into bunkers located at the ends of the cars to maintain temperature control during long hauls, representing a major step up from previous non-refrigerated transport methods.
