I won't deny it!

Now, if you want my honest assessment, I find the whole thing fraught
with ethical questions.

What if someone isn't listening to the radio when the message is
broadcast? What about the people who don't live near railroad tracks?

If this thing is to *actually* work, it would have to be space based.
Work with a database of the frequencies in use in the affected areas.
broadcast on them as the need arises. FM will be easy. AM will be some
more work. Of course you'll still have to deal with the people who
aren't listening at the moment!

Of course if it just a research project to burn up some money, then
*that* is a different subject altogether!

I've got an idea.
How about installing flashing lights at rail road crossing, and maybe some
bells.

Space-based wouldn't work. You can't get a spot footprint small enough on
the earth's surface to make this do-able. Iridium comes about the closest,
but would you put up a constellation to provide the footprints and not use
it 99.999999999% of the time? :-)

Cheers.

If you want to see an unpolite newsgroup, post a home owner message at
alt.hvac and watch it fly.

Trains are a big part of successful evacuation. When Rita approached
Texas, officials asked for more Amtrack trains and got them , though not
enough, to evacuate Galveson and surrounding areas. No reports pf
injuries to evacuees on trains, but many in autos and aboard busses died
in traffic jams on highways.
The nation needs a rail system especially in emergencies.

To believe in gun control, one has to believe that guns are not an
effective means of self-defense, which is why police carry them.
