The Amtrak reports obtained by The Bee reveal the engineer took the train at 78 miles per hour into a track switch that had a 40 mph speed limit. |

So, it sounds like the thought "80 mph track speed, we're at 78, clear ahead OK all good" bulldozed any thought of "there's a diverging route, which means going over a switch set to open, which means 1/2 speed".I've never operated a train. What would the signal look like for that condition? Does it read something like 'green, go, OK' or some version of 'yellow, caution, restriction' ?? |

My take away is that there is more that sufficient safety margins built into the existing system to make the added expense of PTC unecessary. Furthermore, the far less costly technology of Cab Signaling + ATC would have also prevented this sort of incident.The real outrage is that PTC will depress operational speeds through the turnout or other restrictions to below the current limits when the current limits were designed with substantial safety margins to account for human error. Why is nobody setting PTC limits closer to the actual critical points or raising speeds in general? |

There was already a huge margin between operating and derailment speeds, over 100%. It's just easier to dumb down the operation and subsequently deny anything better is possible.Example: In the 1940s, the NYC subway ran more trains, often at higher speeds, over 19th century grade bolted track on wood ties than it does now with continuous welded rail checked by inspection trains with laser eyes. |

My take away is that there is more that sufficient safety margins built into the existing system to make the added expense of PTC un(n)ecessaryIf that were true, then the hogger would have not gone 38 mph faster through the switch than he ought to have. Looks like the hoggers are bringing this on the public by these kind of screwups. |

It depends by whose hands those people died. If the driver was drunk, that's his problem. If the person was being driven by someone else, and that person did something wrong, the finger is going to be pointed at the driver and the organization he/she belongs to. |
