Streamlined in 1950. Stewardess Nurse, One of only 2 all Air Conditioned trains of its day (1932). In 1950, this train was streamlined, complete with two dome coaches. Since this train ran primarily over night, there wasn't much to see from the dome, so floodlights were added in front of the dome and set to various angles to either side of the track, giving artificial moonight to the rural areas along the way (the flood lights were turned off in urban areas).
