ABSTRACT:
A modular vehicle comprises a preassembled undercarriage module, a preassembled overcarriage module, and coupling means for releasably coupling the overcarriage module to the undercarriage module. The undercarriage module includes wheels for permitting travel of the vehicle on a travelling surface, means for holding a power source for supplying operating power to the vehicle, and means for directing controlled motive power from the power source to at least one of the wheels. The overcarriage module includes control means linkable with the undercarriage module for controlling operation of the vehicle. When the power source associated with a first undercarriage module is in need of maintenance service, there is provided a method of handling an overcarriage module coupled to the first undercarriage module comprising the steps of decoupling and separating the two modules; then releasably coupling the overcarriage module to a second one of such undercarriage modules, the associated power source of the second undercarriage module not being in need of maintenance service; then operating the overcarriage module and the second undercarriage module together as a vehicle while providing the maintenance service required by the power source of the first undercarriage module.
