This is an Intermountain N Scale SD40T-2 "Tunnel Motor" Loco, Rio Grande #5373. It is currently DC, but I had planned to install a decoder as my layout is DCC. I am including an N163AO decoder I had planned to install (see photo) if you would like to install it yourself (it is a simple drop-in stall). I bought the loco new about 5 years ago and never ran it. Original price for the loco only was $119. I have since switched to HO so am starting to sell my N Scale collection. This is a great looking loco and would be a good addition to any collection or layout. I will gladly combine shipping. Sorry, US Only bidders. Thanks and good luck.
