Here is a pair of Atlas Diesel HO engines. they are 5910 and 11. Both are lighted and did run when tested, I did not oil them or anything and they have likely sat in collection for a few decades, so be sure to oil em up. I am not a train guy, but these look to be in really nice shape, other than they both need a connector installed in their rear. You get the pair you see, i will have more ho stuff coming, and other toys, happy to combine shipping. Price is for the matched pair.
