I've tried Rob's Rustoleum dark brown camouflage and liked it. Here in the photo below is the track painted from the Rustoleum rattle can and it is rather dark; as Rob noted, it will need some weathering to lighten in up a bit.

I used to go with the Floquil Railroad Tie Brown too.

These days I mostly use Rustoleum's dark brown camouflage. I apply with the spray can wherever possible, but in tighter areas I spray some into an airbrush jar, add some thinner, and run it through the airbrush. For secondary tracks I add some drybrush weathering on top of it with acrylics.

Well, even though it's gone the way of Floquil, too, I found Pollyscale to yield the best results: easy to apply, a bottle goes a long way, and no stink. I still have a fair amount of Pollyscale paint on-hand, so it would be my first choice. I did all of mine, well over 200' of main line alone, using a fairly-stiff chisel-type brush. Once fully-cured, it's very durable, too....moreso even than Floquil.Nowadays, I might suggest Scalecoat, either I or II (chemically, they're very similar, using the same components but in different proportions).There are several newer brands of paint nowadays, too, but many are airbrush-ready, which means that they're not very useful if one prefers to use a brush. While I'm very comfortable using an airbrush, I wouldn't do so for painting rails or ties.

I am hand laying track with Fast Tracks. Since Floquil is no longer manufacturing paints, I am at a loss with how to paint my track work. I used to use Floquil rail tie brown, either out of a spray can or airbrush.
What are you folks doing to paint your track, these days?
