Hello to all. I bought this beautiful model , but now I wanted to weathering according to the picture of a real one, but I cant find any pictures of the Union Pacific version. except those: http://www.rrpicturearchives.net/showPicture.aspx?id=2522996 http://www.ebay.it/itm/Original-Sli...-2-Action-w-Frt-Ft-Collins-1957-/371603904314 any help? tnx Alessandro
Alcos were notoriously called hononary steam engines because of their tendencies to smoke heavy upon getting underway. For starters a light coat of grimy black misted over all the top surfaces would be in order and a little heavier on the exhaust stack. Then there is the soot carried off and down the sides by rain which I would do lightly and sporadic. From the bottom there would be dust and dirt/mud kicked up by the trucks up to the bottom of the walkway. You can see that from the first picture on the stack and faintly on the top. The trucks look like they are fresh out of the shop but look in between them at the side of the fuel tank.
Take the easy route and pretend it's early 1949 when this unit was built and photographed: http://www.snowcrest.net/photobob/upl21.jpg Relatively clean, except for some soot near the top of the exhaust stack. Looks like the trucks may have come from the factory painted gray.
These are not UP RS-2's, but they might give you an idea of the weathering patterns. Interesting to note that the roof top soot patterns on both engines are forward of the stacks.

Thanks for the information and photos . I think I'll do a very dirty version to practice with the N scale. seeya soon whit some photos. ciao Alessandro
Nice shot, taken at San Bernardino. UP diesel trucks were grey, until 1953 and thereafter. This engine was in helper service over Cajon, note the markers. Didn't work out too well... Otto
