I have begun the insidious process of creating new Garden Railroad hobbyists. I have been introducing the hobby to my Father-in-Law and my kids, and they have demonstrated a great interest. As they are not the most reliable engineers in the operator pool, could an extra (or multiple) physical E-stop buttons be added to the system? I envision some type of big red button that would allow me to trip the STOP function on the MTSII remote without dashing back to the central station or ripping a throttle from the hands of a child.

I don't suppose just causing a brief short circuit across the rails would be ideal, as I have no idea the wear and tear this would cause.

I haven't seen any equipment like this in my google searches, but I can be quite dense at times.

Perhaps you could try something like this
1 Channel 12V 433MHZ Receiver Wireless Relay RF Remote Control DIY Switch Module 6430737214557 | eBay
Pass one track lead through the relay so that it goes open circuit when you press the Tx button.
You'll need to lash up a 12v supply, perhaps using a HOT Practical Step Down Module LM2596 DC-DC Buck Converter Output 1.3V-35V 6907389409957 | eBay

Edit, I've just noticed that the first item doesn't appear to have a Tx. I'm sure you could find sets with both Tx and Rx for not a lot more money. You may even be able to get more than one Tx that operates the same Rx

Neil,
Would this be to interrupt the connection to the rails?

Neil,

Yes, that's the idea. I wouldn't advocate any "home made gizmo" on the mains side of the power supply.
