Wiring 15 degree crossing

Layout picture attached. N scale. DC not DCC. 4 Blocks. 2 locomotives running in same direction. 1 power pack. When a locomotive comes close to the other locomotive, it will be stopped by turning the power off the block the back locomotive is in, and letting the front one advance.
?1. Are the outer rails marked in red "common" rails?
? 2. How should the 15 degree turnout be wired & connected with plastic rail joiners?
?3. Is there any foreseeable electrical short problem?
A s long as the trains keep a block space they will both run o.k. ?????????????????????

?1 - Red is usually the power rail but on this track plan it is irrelevant.
?2 - Depends on how you wire it. As it is drawn, it is a block unto itself. Better would be to just have insulated joiners on two legs only. For example put them on the two upper legs, that would make the lower right leg part of block 1, and the lower left leg would be part of block 3. Crossings (not a turnout) are not interconnected, at least not in HO. Each track is powered separately by the track leading into or out of it.
?3 - No.
They will run OK, just pay attention.
