For Sale HO Athearn 3603 Burlington Northern F45 DC Powered Diesel Locomotive

For Sale at ShowMyHobby is a consigned, slightly used, older HO scale Athearn Blue Box Ready-to-Run Burlington Northern EMD F-45 Diesel Engine Locomotive #6615 in its original but modified box. The locomotive runs good. I may have test run it about 4 years ago, but I do not remember for sure, nor was I able to locate a previously saved video. On 1/23/2026, I opened the box and found the locomotive in an incomplete state. The rear coupler assembly was in pieces, no handrails were attached, no front coupler or coupler cover was in the box, and the horn was in 3 different pieces and broken off of the shell. 2 of the door round windows were not installed and only 1 clear circular window was in the box.

I removed the shell first thing and looked at the power transfer bar. It appeared a little rusty. So, I used a fine grain piece of sandpaper and cleaned up all the contact points of the bar, the light, and the 2 contact points that rise up from the inside of the trucks.. I put the circular window inside one of the doors of the shell. I installed the Kadee couple attachments the rear of the frame. I looked through a lot of small parts provided by the Consignor and found the front coupler clip, a Hornhook couplers, and a horn. I installed the Hornhook couplers at the front of the frame. I installed the available handrails to the front of the shell. Although 3 stanchions were found, I only installed the middle front 2. Then, I put the shell back on the locomotive.

Next, I put together a small oval of Bachmann E-Z track on the floor. I put the locomotive on the tracks, turned on the power, and it moves. I have a Burlington Northern graphite pad track cleaning boxcar. I connected it and ran the train for about 25 minutes forward and backwards, most of the time using my track cleaning car. Then I ran them back and forth for about 5 minutes solo. After that, I recorded this video which shows how well the locomotive runs and what it sounds like.

It is a heavy locomotive weight about 1 lb 4 ounces (give or take an once or two). It has 12 metal Medium Flange Wheels (mMFW).

There are some scratches on 1 side of the shell that appear to e arranged like the letters "E Z"... This video was made to provide proof that the locomotive operates as stated..
