I think that the problem with most of the double-deck layouts that I've seen is that the upper level is usually narrower than the lower, mainly to allow the ceiling lighting to illuminate both levels. In my opinion (and my plans for the second level of my own layout) the second level should be as wide as or wider than the lower one. Lighting for the lower level can be placed on the underside of the upper. If the higher section is at or near eye level, an operator won't even see the lower level, and a seated operator running trains on the lower level won't have a view of the upper.
