Planning For The New Staging

I'm doing a little planning for the staging expansion. I have laid out the track in 2", 2 1/4" and 2 1/2" track spacing. I'm hoping for 12 tracks with the outside two tracks mostly to help with restaging. I'm trying to keep the foreground  to under 16",  for ease in getting to the tracks.  It has to go around a corner to get the mainline. 

I usually use 2" centers to keep the space narrower. This has never been a problem for me. However, with the extra tracks I thought I'd take a look.

In all cases the throat used about 4' and about another 8" to straight track.

The first picture shows a track spacing of 2". The table with of 26"

This picture shows 2 1/2" spacing, a 31" table width and a change to a straight Turnout at the beginning. The curve around the corner is a little tighter and the outside tracks to the turnout is also tighter.

This picture is 2 1/4" track spacing and back to a curved turnout.
