A side note. On the Northeast Corridor, I understand they still use the old Pennsylvania Railroad aspect light patterns: 3 horizontal, 3 vertical and 3 diagonal, not red-yellow-green.

I would think they would upgrade the signals, since this was on the Acela line.

Another side note. On the train radio sites I listen too, the Engineers always give information over the radio, every-time they approach a signal. The information I hear seems to always be the same across the board. This information can be heard by the dispatcher and other trains. It is designed to avoid conflicts and possible accidents.

1)State the company(Amtrak, NS, BNSF, etc.).

2)The train number

3)The signal indication they are approaching(green, yellow, red, etc.).

4)Location of signal(either place or mile marker)

5)Track they are using

6)Direction of travel

I do not know if they record the audio but it would be interesting to hear what signal indications the Engineer was calling out on the signals prior to the curve. It could possibly solve the issue with the acceleration prior to the accident (i.e. wrong signal, misread signals, etc.). Also, it would be interesting to hear what the dispatcher has to say, since they control the signals and can hear the audio and would hear a bad signal call-out from an Engineer, and could fix it.
