Planning New Layout, Track Plan Help?

It seems you need a second crossover so that you can return to the outer track without the need to back up. Looks good. Rich

Decided on a track plan, new thread added.

Nice plan, do you have access to the outside areas?  Five feet is a long reach.

I like the layout in photo 1 of the first post.

Edit: never mind on the changes, I like that layout.

Unless your dead set for the duck under I would recommend getting ride of it.  I have a double track main 15' X 28' with a storage yard attached.  The storage yard and outside loop are all on the same TIU channel.  If I have all five lighted cabooses and passenger train running on the loop it draws a lot of amps.  One day I will isolate the yard.  I would recommend some of your storage tracks be isolated with a toggle switch so you can par these type of cars and not overload your circuit.

Ditto on the duck under. It doesn't really seem to add to the overall function of the layout.  I am not an expert by any means but there is a "S" curve in your selected separated by a very short straight section.  Depending on what you run that looks like a potential problem if you run longer equipment.

I agree, I would like the plan in my 12x12 room, except for the duck under.  You could make a lift out or swing up or down section, but I would completely eliminate the connection that says duck under.  Since you have loops around the room, I don't need it.  The aisle may be a bit narrow at one point, but if you only have people trying to pass each other, then it's okay.  All in all, it's very nice.
