This is a used item. It's an N-600, but the connections in the wiring are dirty, so the power sometimes doesn't turn on unless you unplug and replug the adapter. Also, masking tape is attached for layout division. I confirmed that the Nishizawa unit turns on normally. I haven't checked beyond that because I don't have the necessary equipment. Overall, I'm listing it as having scratches and dirt. Vehicle Type...Optional Parts Vehicle Type...Track/Track Options Type...Control Equipment Manufacturer...TOMIX Type...Power Unit/Controller
