This is a K-Line O Golden State Twin Alco and 6 piece streamliner set. It is out of a collection and appears to have been run lightly as there are marks on the wheels and electrical pickups. All pieces include the original box which is in good shape. Please see images and reach out if you have any questions. The boxes have been stored and do show shelf wear and tear.
