Zusammenfassung:	An electronic cabinet assembly is disclosed which is positioned in an exterior environment, such as a railway tunnel. The cabinet assembly includes an electronic cabinet having a box portion and at least one door together defining an interior space. The door has an open position for providing access to the interior space and a closed position where the door is in sealed relation to the box portion. The electronic cabinet includes one or more vents. A fan is in communication with the exterior of the cabinet, and with the interior space. A pressure sensing device is electrically connected to the fan and is in communication with the exterior of the cabinet and with the interior space for actuating the fan in response to sensing a predetermined pressure differential between the exterior of the cabinet and the interior space.
