for those who may be looking I have designed a servo mount for turnout control. im using a 9g servo, levered micro switch with 11mm hole spacing, and .9mm wire to throw the turnout.

its listed on thingiverse as srvo mount for model train turnout. you can also find it listed as servo mount 3B

These are pictures of the rough scenery. The bridge is edging strip normally used to edge tile.

I think I figured out how to add pics. These 3 show the first lower loop set down and my two upper loops on the foam risers

After looking at all the other posts on here I decided to start my own blog. Attached are pics of my coffee table central n scale layout. It started with a 3 by 3 coffee table from a yard sale. I think its an IKEA model but I'm not sure. It measures 37 inches square and the layout itself is 36 inches square. 1/2 pink foam was glued and svrewed to the table top. As there are no turnouts or grades I cut risers for each progressively taller loop from extra foam. The roadbed is also pink foam joined at the seams with foil tape.
