Track plan help and ideas

Hey Guys, I started this track plan last year with help from some Forum members. I got the SCRAM download from the Atlas O website since that was the track I was going to use. I would like to see how it works with Gargraves track but I'm having issues making it fit. This is 3 rail O gauge track and the layout will include Legacy and DCS. Since I have some limited space the max curves I got to fit are 054. I included the current Atlas O track plan and also a drawing of the room with dimensions. The highlighted green track on the current plan was the start of a line that will run below grade, I didn't set track heights yet since I just wanted to see how it would look and work adding another line. I planned on designing it with Gargraves phantom with wood ties and DZ2500 switch machines. I would appreciate any help or advice you can offer. Thanks
