I have Dads old HO table running again, as some of you have heard about already, and I would like to do some enhancements but am not sure just what to do. I don't want to tear it all up and start over but just enhance what's already there, kind of finish up what he started. I'm not sure of the era or setting he was trying to create, the stock is steam and freight and some town type stuff and I'm no great railroad connoisseur, I'm interested in the modeling aspect more than anything, Im just not sure what to model here. There isn't much room but here are a few of my thoughts, can anyone help me decide by making some suggestions?? I know theres some great imaginations out there with lots of experience and I thought I'd try to tap into some of it. Thanks in advance. 
I would like to add some kind of water, a stream or pond.
I would like to add some elevation, it SO darn FLAT. There isn't much room but thought I could add some low stuff here and there just to break the flatness.
I don't know where to put the water tower and coal building thingy (I don't know what its really called) it's in the center rear of the pic.
I plan on adding some raised sides on hinges with a backdrop painted on them, to support a dust cover and add some scenery. The hinges will allow maintenence access. BUT what scenes??? The track is awfully close to the edges of the table.
