On the Walthers Web site I found Weathering Markers from Floquil Polly S Color Corp.
They come in 3-packs. I was curious if anyone has tried them yet. I am especially interested in the Rail Brown as that may be a quick and easy way to paint rail.
I did buy the markers to try them out and there not too bad. I tried em on some ez-track and i used the rust on the rails and the tie brown on the ties. It looks ok, the brown is very brown so it looks only a shade lighter then the black. If I didnt put it on myself I wouldnt know it was there. I also tried it on a old loco to see how it looks and id say they look decent… you need to seal it with something cus the minute you touch it, it wipes off ( and thats after its dried for a while).
I purchased all three packs. I have used the rail brown as well as the tie color from the pack you mention. Extremely useful for touch up work. Not an exact match for the colors I used to weather the track but actually the variety adds to realism. The paint dries very durable and is hard to scratch off. I also like the mud and aged concrete colors in the other packs.
I would say that while the markers surely can be used to weather all your rail, this could be an expensive way to go, particularly since to my knowledge they do not sell any one paint stick separately but only in packs of 3 different types. As with most things you pay for convenience (a non model railroad example is in the frozen food section of the store. Check the price for frozen peas and then the price for frozen buttered peas. You pay a surprising amount of money to have someone else butter your peas for you.)
