|This was the last version of the 30, built in 1949 and 1950. The water tower operates just like the big towers used to - to service steam locomotives. When your locomotive tender has been eased into position, press the remote control button, and the spout lowers over the tender filling hole. Release the button, and the spout folds back into a vertical position. Single wall, light amber tank, dark gray base, brown trestle assembly, dark gray painted tank cover without hole in center, two 30-18 red fiber shoulder washers under 38-65 palnut cover nuts, number "30" is NOT stamped in numbers on the raised plaque on base, compared to the 1949 version with number "30" stamped on the plaque.
