BNSF collision near Omaha
Author: pedrop

Hi, I do not know if it was published in TO before. I am wondering if these trains have Alstom or Wabtech systems like trip optimizer that could prevent collisions like this.

How are those mid train DPU's working out for you (BNSF)

There is NO current technology to prevent rear enders.  PTC is not capable and Trip Optimizer is a fuel saving system.  This type of accident is the blind spot of all the technology.  I'm glad no one was killed.

Dark TWC. And they want to go to one man crews.

What mid train DPs? This was two separate trains

PTC very capable of preventing rear end collisions, just not in dark territory where there is no PTC.

Autonomous trains will eliminate this. They'll be here sooner than most folks think.

What about the End of a Train Devices?

Hmm, I was under the impression that PTC would cover all railroad territory as long as PTC transmiters were installed along the right of way.
Around here they are installed near signals as ours are 2 miles apart and that was what the PTC was supposed to protect.
So did they not install transmitters in Dark Territory?

That tried to become one train..... might wanna back off on the coupling speed!

My understanding is the EOT device does three, basic things:

1.  Gives the engineer a remote reading of brake pressure at the end of the train
2.  Allows the engineer to dump the air for emergency application, from that location.
3.  Flashes a red light for night time visibility.

Unless the following train is going slow enough to stop within the sight distance, none of those things will prevent a rear ender.

Sight distance is only effective if one's eyes are open.

I’m not knocking the non rail members of this board. But there are some major misconceptions about PTC being presented here quite regularly. From the requirements of its implementation to how it actually operates in the field. The technology and the railroads requirements of its use, still has a way to go.

PTC will not prevent a rear-ender under Restricted Speed operation, either.

...or on a Restricting or Stop and Proceed where there is PTC.

...and the railroad industry will lose even more of the capacity that they waste.
