Thanks to all who responded with such great information.

My layout is 8ft wide x 14ft long, with a 4x8 hole in the middle.
I prefer N&W, Southern, RF&P, C&O or other SE railways.

Thanks again. Now I have to choose which to get!

My layout has 22 inch radius curves. I want to get a nice loco for Xmas, but I am hesitant to purchase anything that requires larger radius curves.
I am looking at Bachmann Spectrum trains with DCC and Sound:
     USRA 2-10-2 #83802
     2-8-0 Consolidation #84503
     4-8-2 Heavy Mtn #84203
     2-6-6-2 #84803
     2-10-0 Russian decapod #84305
     4-6-0 #84904
     4-4-0 Richmond #85103
Any help is appreciated!
