We've been through this several times, of course. What this says, for good or ill, is that Metrolink no longer trusts real human supervisors. It would have been easy enough to see from a station parking lot into the window of an F59 that an engineer who'd gotten into the bad habit of texting while at the throttle wasn't paying much attention to his work. But somehow nobody caught this in the weeks and months prior to the collision -- nor did supervisors apparently take much note of the fact that crews had stopped calling signals, which should have been easy enough to find out if anyone had been listening to radio transmissions.

I notice the new CCT Timetable has a whole new section on crews not using personal cell phones while on duty!

But none of this is going to be any good if supervisors don't do their job, either with the help of in-cab cameras or without it. We had (or have) a poster on threads like this who appears to be someone in the chain of responsibility for the Chatsworth accident who for the life of him can't understand how it all happened.
