Just posting some of my layouts. Firstly a standard 4 level up/down oval. Trains go up on the outer track and down on the inner track. Along the bottom you will need a 1/4 track on the short side to change from inner track coming down to outer track going up. If you have lane changers they can be well used on levels 2 and 3 opposite the up/down sloping tracks - changing lane will change train going up to go back down and vise versa.
Next is a more complex version of the standard 4 level up/down oval. It adds inner circles each end that can also be used to change the direction of the train and a quick decent option at the side.
Thirdly is the Triple Spiral Towers. There are lane changers between the closest two spirals. This layout and the above two are on a 180cm x 80cm table.
