Do you guys notice that when you first layout your track on top of the wood board before you place down cork and so on that there are parts of the track if your using atlas section that are wobble or do not rest completely on the board? I working on a new layout and I'm test running it on track just laid on top of board and there are parts of the track that are unlevel and when the train goes over the track it wobbles and the cars sort of sway from side to side as the weight of the locomotive pushes down on the track there is a rebound upward as the lighter cars pass over the track. What's neat about that is if you go to fast you have a derailment caused by bad track and you have to go real slow just like in reality. I wonder if you could lay down cork and then track and then ballast or something and build in the wobble by having unlevel track. Would it be worthwhile? In the goal for ultimate realism would you possibly ruin your layout? I think it would be neat to have a part of a layout where you have to go slow or the train will derail. Any ideas of how to do this?
