And of course no traction tires...
they are surprisingly good at climbing grades because they are heavy, but I wouldn’t try an over/under figure eight without a lot of room. A 2% grade to climb 6.5” in O gauge requires 27 feet of track. Standard gauge requires a minimum of 9.5” of clearance depending on the height of the train. That would be around 45 feet of track. I doubt a standard gauge train could climb more than a 2% grade. Even then, it may require a couple of plateaus. Two 2’ plateaus in a climb, mean you would need about 50’ of track up and another 50’ down. That would fill my entire layout space with 42” curves. You would need a 50’ x 30’ space minimum to do it justice.

George - almost like real trains ?
