Abstract: A baggage cart intended to be selectively coupled to other carts to form a train of carts comprises a body and an undercarriage supporting the body. The body includes a double-walled plastic floor, a double-walled plastic roof, and a pair of double-walled plastic end members. Each of the end members has integral lower and upper extension portions extending toward and being fastened with the longitudinal ends of the floor and roof, respectively. The undercarriage includes a plurality of metal stringer members extending substantially the length of the body and attached thereto. A tower assembly is secured to the stringer members, and a steerable front axle assembly is disposed beneath the tower assembly, with a bearing member interconnecting the tower assembly and front axle assembly such that the front axle assembly is rotatable relative to the tower assembly.
