jward, i love yards but i find with 8' tables it really hard to fit in a nice one.

thanks, i'm still learning about dcc

yes i am aware of the polarity of the tracks leading into the turn table, do any of you know of a way or wiring this with dcc so that it can work, if not i can remove it. With the round house it will be the last thing i add to my layout, i have the turntable and roundhouse already from my current layout so i was gonna play it by ear for what fits.
so definitely im gonna haft to mess around with the positon of the turntable.

but i do see on the right hand side about 3 feet down i could add turnouts and then there is a double oval and the bit in the center

*sorry about all the double posting*

i dont know how well you can see the picture but there is a double track around the perimeter, just the inside track turn into the center but it still makes a double oval

which turnout do you mean when you say "8 across & 3+4 down"? I know there is a different polarity for 1 of the lines going into the turn table but i though i might control the turn table with 1 of my old dc controllers if its possible.
Also with the concern about me using a 18" radius, i am only running small 4 axle engines, no steam engines, would 18" radius still look good or should i try to upgrade to 22"

so after a bit of though would it be good to redisign this with 2 1/4 between tracks and curves starting at 22" instead of 18". think this would work well?

so do you think i should increase the track centers from 2" to 2.25"?

joe your comment is very helpfull, the reasoni though id use small radius' is so i could have more straight track, but ill mess around with a few ideas using bigger radius', thanks

thanks, also thinking of investing in a dcc system instead of dual cab wiring

I am thinking about upgrading my 4x8 layout to something like this:
Any suggestons?
