My layout is about the same size as yours (20 x 30) and here's what I found out about lower level staging yards ( I have two) since you're planning on building one.
1. Make sure you have enough separation between levels but not TOO much. (see #2 below) There WILL be problems down there every now & then and you really need to be able to both see in and reach in to fix things. There's about 14" from railhead to railhead on mine.
2. The grade up to the layout is going to be steep. Mine is 5%. We just don't have enough run length to get the grade percentage down much lower. One, dual can motored diesel with traction tires can pull about 10 average length/weight cars up that grade, and two locomotives can pull almost 20. Die cast freight cars (like some Intermodal cars) reduce that number significantly. Overall I'm very happy with how mine performs. i just had to buy a few more locomotives to make it work (darn it!!  
A helix is the best way to do this, you could make a great looking double-deck railroad with 2 feet between levels, but it looks like you and I don't really have the space for one.
Again, nice job so far. I hope some of what Ive learned helps you with yours.

Hi Rich,
I hear you on the radical, toy train grades needed to make the transition from upper to lower levels. I'm planning to set my lower level 12" lower than the main level, currently set a 40". I know that is tight and will limit viewing, especially with a 22-24" deep deck, but like you said, with limited room comes compromises. I'm considering more grade run to lower it even a bit lower, but I'll mock it all up before I build anything. I figure I'll need to run along all four walls to get down to a 28" elevation, which means another lift up bridge in front of the doorway.
I also need a return loop, which easily be added inside the room, but it would have to be removable when not running trains. I'm planning for my staging yard to run along three walls, so that should give me plenty of yard area.
I also have alot of diecast intermodal equipment, so pushers and maybe even a mid train slave unit will be called for. I look at it as prototypical- all good to me! I t will be interesting to say at the very least how my engines with scale wheels will handle a long intermodal stack train- good thing I'm building a layout that can accomodate 3-rail engines too. I will need that rubber -tired traction.
I'd love to see pics of your layout- feel free to post them here. Any helpful ideals are greaty appreciated.
