Overview of a railcar control panel. Photo by E. Wilde, 2002 Feb 3.

In this overview of a car control panel, miscellaneous controls are on the left (exhaust fans, vestibule lights, hallway floor heat), the 120V breaker panel is in the middle and the three phase power handling, heating, cooling and ventilation systems are on the right. One can easily see, at a glance, how things are operating. Photo by E. Wilde, 2002 Feb 3.

Control panel layout. Photo by E. Wilde, 2002 Feb 3.   A close up view of the major system components shows the logical grouping of the functions. Additionally, the flow of power through the system, selector switches, etc. is denoted by black lines so that one can follow the power from where it enters the car (on the left), through the contactors and selectors, out to the car itself (on the right). Meters and indicator lights are meant to give an accurate status of all of the car's systems. The lamp test button, at the bottom right — it's a classic and we couldn't resist.

The control panel is hinged and swings out for easy access to its rear. Remember. Neatness counts! All of the wiring exits the panel on the hinge side in a single bundle which is looped down and up to a set of terminal blocks where it can be connected to the rest of the car. The loop allows the bundle to move and flex when the panel is opened. Photo by Eric Wilde, 2002 Feb 3.   Control panel, back side. Photo by E. Wilde, 2002 Feb 3.
