Athearn Genesis GP40-2 | Cotton Belt SSW 7257 | Custom DCC | ATHG40926 I’m slimming down my collection selling a like-new Athearn Genesis GP40-2 / Cotton Belt SSW 7257 locomotive. I’ve installed custom silent DCC (Digitrax DH166D), with the locomotive programmed to the road number. However, the locomotive has only a few minutes of test runtime since I don’t have a layout, and it is mechanically/cosmetically like new. Please see the detailed photographs to see its excellent condition.
