Conflict raises it's ugly head?

Well after I got my Viaduct set I really wasn't too happy with it, Im not sure if it was because I didn't have the space needed for the shops add-on or what.

I went on eBay and ordered a V11 - Double Track Set 20-870, I plan to run that set under the Viaduct set so conceivably I could have 4 trains running at the same time.

Ideally Id like to have an up and down section, maybe with the V11 & V13 sets I could do something like that.
