They just don't know any better at this point, and they aren't listening to the conversation. There's no one to argue with what you're saying. They're just flat-out ignoring it.
I thank @Adrian! for adding a deeper technical analysis that clarifies a little better what many of us, including you, have been saying, for quite some time.
The instant breakers aren’t meant to protect against voltage spikes. They’re meant to open the circuit as quickly as possible to minimize the time a derailment is sparking, arcing, etc.
Adrian’s explanation of TVS diodes is wonderful, and explains why placing them as close as possible to the electronics is the best way to install them.
Personally, I recommend both TVS diodes and quality circuit breakers for all layouts that have Protosound, DCS, TMCC, or Legacy locomotives running on them.
