I have here a 697 track trip to operate different accessories on the layout. I have use it for a block signals and to throw switches to prevent derailments. You may have other reason to use it. I have change my layout and do not need this anymore.THE ABOVE DESCRIPTION IS TO THE BEST OF MY KNOWLEDGE . PLEASE ask any and all questions before bidding (and winning). I do not rate my items but, I may say what I think what they may be. Flat rate shipping charges are of my own not that of the USPS or of E-bays. I have other items for listed at this time so please look and see if you want them also. I will combine shipping charges when more then one item is bought. And will wait on items ending at different times. But won items need to pay for first and will discount or refund later on others items.
