Uploader comment: This is the main control panel where you run tests on the computer. This computer was used for the classification yard, hump yard, at Little Rock Arkansas. A classification yard is where cars are sorted to make up trains. Anytime someone had to work in the classification yard while cars were being sorted you had to keep on your toes. They are amazingly quiet and if you weren't careful you would find yourself coupled between two cars. If you think your computer heats the room up this one would turn it into an oven. They had to use large air conditioners in this room even in the winter time.
