In some places, a teamster was called a carter, the name referring to the bullock cart.
[1] Originally the term teamster meant a person who drove a team, usually of oxen, horses, or mules, pulling a wagon,[2] replacing the earlier teamer.
A teamster might also drive pack animals, such as a muletrain, in which case he was also called a muleteer or muleskinner.
[4] In Australian English, a teamster was also called a bullocker or bullocky[citation needed] and was sometimes used to denote a carrier.
[5] From the Revolutionary War at least through World War I, United States Army enlisted personnel responsible for transporting supplies by wagon and for the upkeep of those draft animals were called wagoners.
