My father used to commute to work on those beauties, and occasionally I travelled with him. Pennsy, remember they needed a conductor between each two cars? (Four conductors on a six-car train!) And they used a bell cord to relay "gates closed" from the rear of the train to the front. No luxuries like centralized door control or even an electric buzzer. Wooden trains and iron men.
