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. The baggage cart further comprises a tow bar pivotally secured to the front axle assembly, a rear axle assembly attached to the stringer members, and a hitch attached to the stringer members and capable of releasably securing one of the other carts. The inner walls of the floor and roof include conically shaped depressions having complementary-shaped spacers or plugs disposed therein. In addition, a plurality of metal tubes are supported between sockets formed in the end members, and a plastic shelf extends over and is supported by the metal tubes. The baggage cart also comprises a brake arrangement operated by the tow bar. Furthermore, a method of assembling the cart body and securing the cart body to the undercarriage is disclosed.
