Like I said in another thread, "Emergency" implies IMMEDIATE (not planned)
danger to life, limb, or property. It seems that, in your proposal, you are
PLANNING to use these frequencies instead of more appropriate ones. I would
think that you need to create (and supply) a system that is isolated from
broadcast frequencies.

DHS has proposed a change in scenario. They want an on locomotive alerting
system that could be commandeered and driven at, near or about a disaster
site. Everything else stays more or less the same, overbroadcasting on
local AM/FM, power off the locomotive, selective or full frequency
broadcasting, train (s) to be in motion at all times. 20-30 second
messages
that would also combine a message to be aware that a locomotive (at speed)
will be flying by the at grade crossings.
