Okay so I guess you mean you were inferring from the FBI entering the investigation, that it meant the CSX crew or crew member swore they had lined and locked the siding switch back to the main track position. Judging by some of the reactions to your post I don't think that was completely clear to some people. I have been waiting for the NTSB to give some indication of what the CSX crew said. They interviewed them last Monday.

I would guess the CSX crew member who was supposed to have lined and locked the switch back to the proper position isn't going to say anything other than they are quite sure they did so. They apparently filled out a switch position form attesting to the fact. Not likely, when asked by the NTSB investigators, that they're suddenly going to remember that they
didn't line the switch back to the main track position.
