An ore hauler is a type of vehicle used to transport ore from one place to another. The term can refer to three different types of vehicles: a tramcar (7 letters), a TRAM (4 letters), or a SCOW (4 letters). A tramcar is a rail vehicle that runs on tracks and is powered by electricity. A TRAM is similar to a tramcar, but it is powered by an overhead cable. A SCOW is a flat-bottomed boat that is used to transport goods across water.
