At least one of the switches in the next town east on the Kansas City Southern has been radio-operated for a while. The engineer or conductor could key in some numbers on their radio, which were transmitted as DTMF
on the air. Once the switch actually moved, it would transmit a short single-tone beep as an acknowledgement.

Looks like the railroads have finally realized the potential of "power-operated, remote-control" switches that could be thrown by other
than train dispatchers (at CTC consoles).
It's certainly cheaper than paying a brakeman or conductor to "walk 'n' throw" them!

The Alaska Railroad has been doing this for some time. It's a lot safer
for the crew member who doesn't have to go outside when it's 60 below to wrestle with a switch.

To avoid laying "physical wire" to each location, perhaps some kind of wireless/satellite technology could be used to convey the state of
each switch back to the dispatcher's office...
