With any company that operates without dispatching, which you can do if you're never going over yard limit speeds, it's still technically a main line but do you need the LVVRs? I'm sort of wondering. I think we've killed that one.
Another point is this. Do you have specific examples of where LVVR has actually helped an investigation? I think one of the best known ones is the Kismet investigation in 2006 when two BNSF trains collided. It's really a spectacular video, but was it important to the investigation or is it just a spectacular video?
