    Advice needed for feeds and insulators

    I would like some help on determining where I need connections for power feeds and insulated rail joiners for the track below.

    BLUE is for power feeds to the track.

    RED is where I already have insulated track joiners.

    Yellow is where I suspect I need an additional insulated cut to eliminate shorts.

    Please add for advise for where additional power feed and insulators will be required.

    heres the track plan

      Dave,

      The rule I learned long ago is that you cannot have power reaching the frog from the end away from the points. So I always gap both rails near the frog. I always feed power to both rails on spurs because to allow expansion I don’t solder track joints. (Do you?)

      However, the locations you circled in yellow do need gaps. I see another spot also needing a gap.

        Mike, other than where I have noted so by insulators,everything is soldered.

        So where is the spot you see that needs an insulator? Is it between the two turnouts just above the crossover?

        I was thinking those two turnouts will always be thrown in unison as a runaround track.

          Dave,

          Yes, that’s the spot I was looking at. If, as you say, the two turnouts are thrown simultaneously you should be ok.

          I really like your trackwork with its complexity. Looks very appropriate for a dockland area.

              Any other opinions or suggestions out there? Lets hear them.

                or back drop. One of mine too.

                You are isolating your frogs?

                Are you using DC or DCC?

                  Dave,

                  I would add several insulated spots. The longer spurs (right after the turnouts) and make that trackage a separate block. Then if you pull an engine out on the spur, you could kill power to it. Of course another advantage is to create some isolation for possible troubleshooting shorts, etc. Biggest problem I see is folks thinking DCC = unnecessary or no blocks. Bites them right in the @ss, more often than they thought.

                    I would still cut the gaps to be on the "safe" side. Or, run your layout for a while to see if it is an issue.

                      I solder all track joints after I am satisfied with the running characteristics of the layout.

                      Also, when I gap track, I fill in with a small piece of styrene. Keeps the gap but does allow for some expansion.
