When we rode the Amtrak Empire Builder there was of course the train crew,Conductor, front & rear Brakemen, & Engineer. The service crew consisted ot a Porter for each Pullman, a Porter for each two coaches. The lounge car attendant, The diner had the four Cooks a Steward and three Waiters. I was surprised to find the Steward was a woman.
The Conductor and the rear Brakeman were in dark Blue uniforms. The Porters wore white jackets with black pants. The Steward wore black pants with a red jacket as did the Waiters. The Steward's uniform had a white trim on the sleeves and collar where the waiters didn't.
