LGB 65011 Sound Unit Power Storage

For analog operation, this high-energy accessory powers your LGB 65000-series sound unit when the track power is off. That lets you hear the standing sounds for a time after the loco stops. (On MTS layouts, the track is always powered, and this accessory is not necessary.) See also 65000, 65001, 65002, 65003, 65004, 65012 and 17050.
