I am concidering adding an addition [3x6 ] to my Scenic Ridge layout. I have enclosed a sketch of the possible track layout which was done on Atlas freeware although I am using Kato unitrack,and the sketch is not exact. I have 3 demensions I must adhere to. The top track must be 2" from the edge, the two tracks marked A & B must be 30" apart to line up with the older layout. I will have to put a #6 turnout on top for the connection. There is a 2" rise from track B to A . The tight curved track will have to be 9 3/4 . I am already running on some 9 3/4 curves without a problem. Any suggestonsAny Suggestion!
