I don't know that. I know that since that time there's been technology in place, through the Wi-Tronix, that can evaluate whether there is a cellphone signal being received or transmitted from a locomotive. It can tell you if a cellphone is on in a locomotive. That technology exists. Most of it is already installed on a locomotive, so if they really wanted to go after cellphones they could flip the switch on that and tell you if a cellphone is on and could investigate that.
There is no need to have live video monitoring. It's something the airlines don't have, something that no other country has. This would be a first in the world. To institute this type of technology with employer access at this level would be a first in the world. I simply don't see a need for it when you have the technology that would do exactly what you ask.
