can anyone tell me what is the closest match for DRG& W orange and if is it available in spray can form?
What specifically are you looking to paint?
Badger Modelflex paint has a nice Rio Grande Orange (16-61). I used it to paint my G scale speeder:
It is not available in spray cans, but it is relatively easy to airbrush. Relatively meaning a little harder to clean up after painting then a solvent based paint, but manageable.
Scalecoat has a paint called D&RGW New Orange that is very similar to the Modelflex Rio Grande Orange color. This is also available in a 6oz spray can. If you’re painting plastic be sure to get Scalecoat II. D&RGW New Orange Spray for Scalecoat II is #20406. Scalecoat I is for wood and metal and could potentially eat away at some plastics. D&RGW New Orange Spray for Scalecoat I is #10406.
To compare the colors, below are color charts. Finding a Scalecoat color chart online is tricky but I did manage to find one:
