The way I understand the current reporting, both trains were told to proceed, then the crew of the train in front reported they couldn't start their train, and, apparently due to the command central being in chaos, the train that was now on a collision course with the train in front of it wasn't stopped. Tragic either way.The central command told the second train to proceed. It's not yet known why and everything would have been ok otherwise.
