<<BNSF (Burlington Northern and Santa Fe Railway) has started to deploy Wi-Fi wireless LAN systems extensively in rail yards to allow crews to remotely control engines used to make up trains. These Wi-Fi systems are connected to a control panel that mimics the control panel of a diesel locomotive -- "You can even blow the horn," Campbell said -- and are both more efficient and less hazardous than manned locomotives.>>
Thanks, I didn't know about that one. For more on WLAN and trains, google the following:
-NetSeal Avecra (in-train restauration's cashier syncs with station's mainframe) -Virgin in UK (WLAN hotspots alongside tracks) -GNER in UK -Click TGV in France -PointShot in the Bay Area -last IETF in Japan, train from airport to city. -I think there is a WLAN'ed train in Finland too.
So at least we know one place not to take the WiFi-enabled horde that is the IETF road-show!
I think IETF'ers went to Japan and tried a WLAN'ed train near Tokio.
