Proto 2000 series HO SW9/1200 Locomotive. Chesapeake & Ohio 5093. I honestly am not familiar with trains. I am offering this for sale according to what the box and engine says. Included is the one Locomotive. Instructions included. Please look at the pictures for the best description. You will receive train that is pictured, box and Instructions. This has not been tested. I will be happy to attempt to answer any questions. Thank you.
