5778c&o Atlas GP40-2 #4164...
The last GP40-2 of the first order for Chessie (4100-4164), these units were built originally with ACI cards and no slotted battery box cover.  Over time some ACI cards were removed and some battery box cover doors were replaced with the famous slotted door.  They all came with the classic Chessie rock pilot on the front under the coupler and a wedge shaped rear plow, since foot boards were outlawed.  #4164 is shown here in its post-April 1984 standard Chessie Paint, typical for a Phase I GP40-2.  Before 1984, this unit was numbered GM50, and was painted all gold.  It kept the 4164 roster spot, the entire time it was GM50.  For the photo I had of the unit below, the ACI card was removed and the original battery box was still installed.

To make the unnumbered Atlas unit more correct I added "B&O" and "4164" decals on the cab and "4164" for the four numberboards.  I added a Details West rear wedge plow.  I painted the MU hoses the correct colors, silver on the tips and red, yellow and green at the tops.  I also painted the wheel faces and the couplers rust color.  Something I do to all locomotive models that make photos look better is to paint the back sides of the steps and pilots and the underside of the sills black.  See the bottom photo to notice how dark the area on the inside of the rear pilot looks.  This area comes painted yellow out of the box and would really stand out, had I not painted it black.  Also, the coupler knuckle basket can be seen in the prototype photo below.  It is on the walk way behind the first vertical stanchion behind the cab.  I have ordered this part from Plano, but it is not installed in my model photos below.  This was a feature on this entire order of GP40-2s.  I weathered the unit after adding the decals to show some road use.

Below is the prototype photo of #4164.
