I've had the all the turnouts wired for several years but only now have been able to get the layout to a point where it is mostly functional. The layout can handle five separate trains and a shuttle. As I am testing the individual tracks I am noticing that the trains tend to stop at various sections of track around the turnouts or short out. At the time I installed the turnouts, I did not know about the fact that insulating pins are required at certain sections of the track. I am seeking some advice as to how best to handle this situation after the fact, since the track is all installed and ballast. I know I can simply use the Dremel tool to cut the track where required but I am not sure where the sections that require insulation be placed or additional wires need to be installed. Are there diagrams that illustrate where one should place the insulating pins either before or after the turnout so that the trains do not stall on the track sections connected to turnouts. I have included a copy of the actual blueprint plans used to construct the layout. Each track is separately wired and are identified with the capital alpha A - E except perhaps where turnouts are, which is probably contributing to the aforementioned stalling and shorting out issues.

If you are running one power source only then there is another issue at play that isolated track track won't fix. In this case the symptoms you noted indicate to me crossing power with ground wires somewhere.
If you are using more than one power source then isolated middle rail (power) is necessary. Power districts which is a group of track powered by one transformer separated from another group of track powered by another transformer are usually defined by turnouts. Straight through is one district and the curve section defines another power district (middle rail isolated). I like to place the insulator one track down from the turnout so I know the turnout rails are always powered. If one district is on while the other is off then the locomotive will stop as soon as its rollers cross over the insulated pin. If one district is at a different voltage then the other the locomotive will spark making the transition.
The only time the outside rails are isolated is if you are using a section of rail to control an accessory or for non-derail.
You will want to isolate/insulate each center rail where seperatly powered tracks meet, as well as at any switch rails that have a non derailing feature. You'll have to check the internal wiring of the switch rails to see where you'll need to add power feeds to any dead spots in the switch. I don't know if the atlas switches include a diagram on internal wiring.
If you have an extra switch you can hook up power on the bench and create your own basic diagram
Depending how your powering the layout , if using more than one transformer be sure they are phased properly (search for threads on that). That could also cause "shorting" while passing over a switch.
