These units started out as factory painted Kato SD40-2's...I dismantled, stripped, redetailed and repaired, abrasivized and repainted these units. Added were plows, mu hoses, cut bars, firecracker antennas, new horns, new grabs, ACI tag holders, eyebolts, speed recorders and so on.
The painting was done with custom mixed Scalecoat II for the yellow and red over gray primer than white. The underframes were painted with Scalecoat II NYC dark gray. The handrails and grab irons are painted with Modelflex Rock Island aluminum white.
The decals are microscale from several different sets, and the entire unit was semiglossed with half Testor's glosscoat and half Testor's dullcoat thinned with lacquer thinner.
