cart was a light, one-horse (or more usually pony), two-wheeled vehicle with road springs, for the carriage of passengers on informal occasions. Its name varied according to the body mounted on it.
An Australian spring cart was a simple cart designed for carrying goods and did not have seating for driver or passengers. The driver usually sat on the sacks or goods carried. The shafts were wider than usual to accommodate a draught horse or a part bred one.
