Yes, regular old greensand, which is getting to the point where I am seriously considering upgrading. No secrets, really. If you are doing small parts, you may want to look into getting some petrobond sand, the surface quality and detail you can get will be worth it. Same techniques, venting isn't as critical, but it is harder to recondition.
Biggest secret, and 90% of casting sucess is a well thought out and finished pattern. I am still but the merest amateur at this art form. I still find out more often than not "That didn't go quite as I expected..."

It's encouraging to see green sand castings with that level of detail! Also, nice job on the caboose. Thanks for the advice, John

Been working on my bobber caboose, adding the final details so it's not just a box on wheels. I have been going back and forth on what to do for the bolts that "attach" the journal pedestals to the frame. They are really screwed on from the bottom, so the bolt holes on the side are a little redundant. But, that was how the prototype was, and it could be attached that way, so that's how it was cast.
Hex head bolts wouldn't look right for the period, so I decided to go with round headed bolts, with the screwdriver slot filled with JB Weld. Problem was, I couldn't find any that weren't flattish, the dome didn't look right.
Then I hit on an idea, I took a roundish headed bolt and attacked it with a file. A little elbow grease and poof, square head bolts with the correct looking crown to them. They also look like they have a washer behind the bolt head. Bingo! I made up enough, and I think they look pretty darn good, way more period correct. They aren't perfect squares, but close enough.

That's really clever work on those bolts OD, Nice.

For what it is worth, a few companies make square-head bolts. Old fashioned blacksmith supply places do, and I used them a bit on my engine. Your idea is pretty creative though.

Thanks guys. Truth be told, I didn't look very hard around here, really. But, all the common "big box" stores had very similar offerings, so for something non-structural $0.97 from Wally Werld seemed like a nice price. I'm not sure that anyone would carry square head in 8/32. Probably not much demand for them. Got the undercarriage more or less completed today, I'll post a pic later.

The catwalks are on and the ends are no longer naked! I'm pretty happy with how the railings came out, they are steel rod drilled through and brazed so they should be plenty rugged. The railings aren't on permanently yet, still have a few things to do to them. Couldn't resist taking a pic to see how they look. Next is ladders, I think I am going to use the same method that I used for the railings. Oh, and a picture of the undercarriage, as promised.

Cupola ladders are done, they turned out nice! Big ladders over the next few days...

Latest parts, the ladders for the ends. These were interesting to do, lots of holes to drill in thinnish round stock, and lots of brazing. They aren't perfect, but close enough. The real fun part was when I was trying to braze one of the rungs, and the way I had it held in the vise caused it to droop and break off at the drilled hole. Oops. I managed to get it brazed together and you can't really tell where it broke.
Next steps are to finish a few details that would be hard to do with the railings and ladders installed and then permanently mount the railings, etc.

These little details, looking really good, by the way, will make the bobber look amazing. All trains deserve a caboose!

Here's what the ladder looks like on the caboose...
