I picked up an Atlas GP40 the other day and was impressed from what I had ever had (my orginal roster before the new loco was 1 atlas Trainman GP38-2, and a dumb Athearn GP40-2 R-T-R-srry athearn!). The detail was incredible and the running quailties was what I expected from a top line company. My model is a Silver series as I have yet to get DCC or sound. The shell is perfectly molded and I have yet to find a inapporpiate detail to the prototype. I did remove the drop steps, rear pilot kickboards, and horn of course. Other wise, a couple of details such as a beacon, 2 radio anttenas, and maybe a liitle paint will finish the model off.
Also, a couple of questions. Where were the roof top details (horn, beacon, and antennas) placed? And the stock Atlas horn - will it work protoypicaly or do I need a new one?
