I'd like to build an "X" cross-over between my two ovals and I'd like to use 4 USA Trains #6 switches and an Aristocraft 19.5 degree cross-over. Will this work, or will I have to cut track or ties? Has anyone every built one using these sectional pieces? I don't want to have to purchase additional switches, but I'm willing to buy the cross-over. Please advise.
