First up is a former Reading C630. This is a Bowser Executive line C630 and I really could not find anything to add to the locomotive. I did an overspray of dull coat to flatten the finish. I then did an oil wash to highlight lies and grills. I than used Pan Pastels to to the balance of the weathering.
This is one of Conrail's 10 C30-7. It is and older Atlas model that I added a plow, antenna and train control box. I weathered it the same as the C630.
The Amtrak F40ph is from Rapido. Agian I could not find any thing to add detail wise. Weathered with Pan Pastels only, it represents a fairly new, well maintained locomotive.
