I'm sorry. Can I just interrupt for a second? I'm trying to conceptualize this.
Let's say a derailment happens in the middle of a large urban centre. You call the firefighters and they'll go online—no problem—and they'll figure out or be able to assess what's on the railcar.
How about some faraway municipality where there is no Internet access, or where they have difficulty that day accessing the Internet, or where there's just one person at the booth because the derailment happens at night? There may not even be somebody there because that person is outside smoking a cigarette or on a coffee break or whatever. What happens in that situation?
How do you compare both of them? How do you make sure the firefighters are not just properly protected but also have proper access to information?
