This train engine is built from discarded auto parts, sheet metal, nuts and screws, as well as discarded pieces from a die machine. Once Armando RamÃrez builds the locomotive's main frame, he uses die pieces to form the boiler. Car bearings are ideal for shaping the train's wheels. Please note it is the artist's intention not to give his sculptures a fine polished finish, therefore smudges and scratches may be present.
