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.

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.
