Hey Gus, hope you have been doing well.
Here is the situation:
With the frog powered, running from frog to point with the points wrong causes a short because the frog is the wrong polarity. This stops the train before it has a chance to run through the incorrectly aligned points. On my layout, this shuts down the command station and all locos on the layout screech to a stop.
If I deleted the frog power, the train would continue and run through the incorrectly aligned points, and generally would derail as the wheelsets jump over the points. Just from past experience, the heavy locos may not always derail, but at least several of the cars are going to derail.
In our 3 hour ops session, with three crews, we probably messed up like this about 6 times. I won't even hazard a guess as to how many times we ran from frog to point and got it right - so we could do a percentage mistakes kind of thing.
