I treated myself to getting back to an old hobby but The fun isn't starting.  Wanted to set up a 2 cab system with 4 turnouts and 5 blocks.

I looked for  insulated rail joiners  but code 80 atlas didn't fit and at any rate, removing Bachmann rail joiners damages end of track rails.  Researched "Bachmann  9" Terminal w/Insulation Gap" package but only comes in HO (why is That?).  Saw a thread that said just cut a gap in tracks but I'm concerned that will weaken the track and ruin 10+ track.  Atlas and  others seem to have an easy solution but I bought my track before I got this far.  If I do have to cut rails do I cut both rails - any particular point - straight or curved-add glue/epoxy to gap?    Any help?
