Insulated K track crossing - suitable for dual operation?

Does anyone know if this K track crossing is suitable to use in a Dc / AC/DCC operation (no 2258)? Thank you.  K track crossing |

As far as I remember, the K crossing does have plastic isolated rail sections (lower left, upper right) that separate the rails at the crossing point. I am not sure if the rails are connected on the underside though.

I can check for you tonight but I am pretty sure only the wide radius turnouts and crossover/double slip have isolated rails. |

Hope that helps:  The black rails inside the circle are made of plastic, although the two wide studs in the middle are (naturally) made of metal. |
Gone insane. Back soon ! |

I think it is a Mike question but let me offer my views on the picture. I think the insulation in the above picture on the top and bottom rail intersections is weak. There seems to be very little gap between the rails. I think there is a 2nd problem in DC. Given the inside of the crossing rails seem to be all plastic, you will have a break in the current. The below is a standard DC crossing. You will see the rails inside the crossing are metal to provide current continuity. You will also see a higher amount of insulation where each rail crosses.

Thank you for your feedback, guys, much appreciated. What do normally DC users do then, do they use crossings or avoid them out of concern for the current interruption/polarity issues? |

If a DC user uses the crossing that I showed, there is no current interruption or polarity issue. I have two on my layout.
Let me also clarify my previous statement on current interruption. I was referring to the k track crossing and using that with DC. The crossing I included has metal rails in the middle of the crossing and thus there is no current interruption issue.
Thanks

I remembered about this questions and fished around for my crossing to check it today.
I can report that the rails are not isolated, they are electrically connected. Interestingly though, the left and right sides are completely isolated (looking at Old Guys picture) |
