An insulated food tray transportation wagon. The single-piece, low-weight, insulated food tray transportation wagon is equipped with sliding panels designed to wedge into place by either friction at any intermediate position to limit the need for an external locking mechanism or by using a step-based notched locking mechanism. The wagon also provides for a flat-panel geometry system, a thin, shell-molded casing made of flame-retardant material and shell insulation for reducing the weight of the wagon. The wagon is also equipped with a series of bottom drains, a kick plate and a series of top handles for maneuvering the wagon. The wagon is equipped with a flat, beverage-holding section located above the wagon, symmetrical handling devices for pulling and pushing the wagon from all sides, and alternatively, a sturdy pivoting hitch to connect a plurality of wagons for simultaneous transportation.
