Runaway MTH O scale engine emergency stop temporary solution?

Per the DCS Companion, "Tap Emergency Stop to shut down power through all TIU channels and necessitate a power cycle of the TIU."  Just to be clear, the TIU stops the power, it still is receiving power, just not passing it through.

Cheryl, thank you for your quick response to my question. I read this statement in the DCS Companion and I pretty-much felt that all power is removed from the tracks, but was worried that if the TIU were still receiving power, could that power (still) somehow transfer to the runaway, or any other, engines on the tracks? I'm probably being overly cautious about this, but if one of my Big Boy engines should fly off the tracks, without a full-proof way of avoiding this event, it could cost dearly. All the best to you Cheryl and thanks again, Lou

There has been situations with several of our club members having their engines take off when track power is barely given to the track not giving the operator time to go to it on the Remote. If possible I would have an MTH guy check it out to see if it is a bad board.

A short on a layout will often cause a DCS loco to start up, and occasionally to move.

Although it is a major issue, I'm not as concerned about the runaways as much as I am about my ability to stop the engines if and when they take off on their own. And Tim, I believe all boards are good, but I'll be checking things out in due course. Thanks to all...
