This standard, water-tite, exterior electrical enclosure can be
fabricated out of carbon or stainless steel. It features positive
closure of the cover against a closed-cell neoprene gasket, glove knobs,
for easy access by railroad personnel, and plenty of room inside for
components. Plans for fabricating it can be found in the
documentation section.

The standard enclosure easily accommodates an electromechanical diesel
engine starter. To the left is a magnetic starter for the electric
radiator fan. Top right is a circuit breaker for the fan and start/stop
pushbuttons. Below them is an hour meter and underneath it are the
starting and shutdown relays plus timing and other control relays. This
starter (whose plans can be found in the
documentation section)
can be used with remote pushbuttons and/or a solid state engine
controller.

Here is another use of the standard enclosure, to house the controls
for an airconditioning unit. At the top are a pair of motor overloads
for the dual condenser fans and next to them is the compressor
contactor. The high and low pressure controls along with pressure
gauges are below. Plans for airconditioning controls are in the
documentation section.

The standard enclosure has been cut into the side of an equipment
housing where it contains the controls for a freeze protection unit. At
the top left is the starter that controls the circulating pump. Right
and below is the contactor for the circulation heater. Bottom right is
an outdoor ambient temperature sensor which turns the unit on near
freezing temperatures. In a separate compartment are system filling and
draining valves and a test port. Power and control wiring is being
hooked up in this picture.
