The LC+2.0 Hudson I own has a drawbar that contains contacts to connect the loco and tender. While looking at the pacifics like the one in the "subject" it looks like it has a standard drawbar (no contacts). I don't see a wire in the picture. Are these units optically connected? Or is the wire hidden in the photo?
