Definition & Explanation

When a refrigerated vehicle pulls into a rail terminal or distribution depot, keeping the cold chain intact during the stop is the central operational concern. Dual-mode reefer vehicles handle this by powering their refrigeration unit from either an onboard diesel generator or an external electrical connection, switching between sources as conditions require. Running on grid power during extended depot stays cuts fuel consumption and reduces wear on the refrigeration engine compared to continuous diesel operation. In intermodal cold-chain logistics, this removes the need to swap reefer units at every modal interface and supports compliance with temperature monitoring documentation. The term should not be confused with fully electric refrigerated vehicles, which rely solely on battery power.
