Have to disagree. The engineer was stopped between signals and if he couldn't see the next signal he was required to proceed at "restricted speed" which in short is a speed that he could stop within one half the field of vision. If he entered the block on "color" which he undoubtedly did then he was required by rule to proceed at the restricted speed requirement. The engineer forgot where he was and what he was doing...easy but I would assume even easier to do while texting. Really doubt if anyone tampered with anything.
Then tell me how a train either doesn’t get routed to the siding , or gets back on the main track, without the switches being changed.
