In the steam era, many railroads used turntables to turn locomotives for their next journey. Railroads still use turntables to assist in the maintenance of diesel locos and rolling stock. Based on a Santa Fe prototype, Atlas O has realistically duplicated its features in true O scale dimensions and details so adding a working turntable has never been simpler. What"s more, everything is included for easy tabletop installation. NOTE: Locomotive not included.
