Train Mounted Camera Battery Charger

This circuit will keep the battery for a train mounted camera charged and will shut the camera off after a few seconds when power is no longer applied to the track. The circuit is designed for DCC systems and the battery is essentially used as a capacitor as it is not allowed to become discharged. The battery also controls the voltage to the camera as any current passed through R1 that is not needed by the camera is shunted through the battery. This is an inefficient but cheap way to control the voltage.
