This is a steam powered push-pull train, in Great Britain called "autotrain", with former British Rail cab car # 233 "Kingfisher" in the rear and 0-6-0 PT tank steamlocomotive # 6412 pulling. leaving Staverton on the South Devon Railway for Totnes Riverside, during the heritage open days. The car was renovated till last year and is in a nice marron paint now. In the "autocoach" service a locomotive fitted with additional control equipment is used to power the autotrain. When running 'autocoach first', the regulator is operated by a linkage to a rotating shaft running the length of the locomotive, passing below the cab floor. This engages (via a telescopic coupling) with another shaft running the full length below the floor of the autocoach. This shaft is turned by a second regulator lever in the cab of the autocoach. The driver can operate the regulator, brakes and whistle from the cab at the end of the autocoach; the fireman remains on the locomotive and (in addition to firing) also controls the valve gear settings. The driver can also warn of the train's approach using a large mechanical gong, prominently mounted high on the cab end of the autocoach, which is operated by stamping on a pedal on the floor of the cab. The driver, guard and fireman communicate with each other by an electric bell system.
