FasTrack switches and fitter pieces

You don’t have to use the fitter pieces, but then you’d have to trim the roadbed on the switches. If you look at the fitters, there are 2; 1 with the roadbed missing on 1 side and the other with the roadbed missing on both sides.

Also, you may need to use those fitters to electrically isolate track connections. They have jumpers to bridge the gap in the 3rd rail.

There are no "insulating pins" for Fastrack, instead, these small sections are used.

There are DIY methods, just saying, this is what was intended factory OEM.

Like you said a DYI is just to dremmel a cut into the 3rd rail.  Easy and effective.  I've found that if the switches are part of a curve (at least on the O72s) then using the filler pieces doesn't work.  The curve is an O72 without the filler.  With the filler it throws off the geometry of the curve.  In that case I just trim the road bed of the adjacent curve.  In the picture below you can see where I trimmed the roadbed and where I made a cut to isolate the block...

Thanks. So it looks like, I can essentially track plan as needed, with or without the fitters, but there may be times where I will need to trim the roadbed for a seamless fit.
