After som more planning, I have changed the mainstation area, to give space for a hidden staging area. The old station has been rotated, and behind it now is space for a staging yard, hidden under the elevated city. That means that the maintrack level, looks to be lower than the cityscene behind it. The cityscene will be mounted so the buildings can be taken out to acccess the staging yard.
The lower level has also been modified to give space for the rotated mainstation. The sigle topevel is cahnged a little, to be incorporated in the city. The rest of the layout is not changed from the previous revision.
I think this new concept on the cityscene will make a better layout. Check out the new revision.
