International Railroad Discussion > Collision of the Vale helper locomotives (Brazil)Date: 02/21/21 17:44 Collision of the Vale helper locomotives (Brazil) Author: pedrop Hi, today a couple of Vale locomotive helpers collided into the end of a ore train in the Carajas railroad (EFC). These helpers use a computer program to coupling and uncoupling "on the fly". We do dot have information about what happened. Watching the video, we perceive the ore train stopped and the helpers had no time to stop.
1 - 3) The ore cars that received the impact. Pedro Rezende Vespasiano MG, Edited 1 time(s). Last edit at 02/21/21 17:56 by pedrop.    Date: 02/21/21 17:45 Re: Collision of the Vale helper locomotives (Brazil) Author: pedrop 4 - 6) More...

Date: 02/21/21 18:37 Re: Collision of the Vale helper locomotives (Brazil) Author: krm152 Super awesome video; at the right place at the right time.
Plus, photo series is thorough an interesting. Thanks for the great posting. ALLEN Date: 02/21/21 19:16 Re: Collision of the Vale helper locomotives (Brazil) Author: sp8234 WOW, Nobody was in the engines?

Really interesting video Thanks Pedro. Date: 02/21/21 21:03 Re: Collision of the Vale helper locomotives (Brazil) Author: Ritzville Wow, a very interesting video of the computer malfunction. A bad day on the railroad.

Serious video. Surprised they have unmanned helpers with that task, but I guess it was working at some point. Edited 1 time(s). Last edit at 02/21/21 21:21 by TCnR.

Date: 02/22/21 02:44 Re: Collision of the Vale helper locomotives (Brazil) Author: pedrop Here is a video of how this Dynamic helper works. It is narrated in english youtu.be/jrexizikrzs

We do not understand what really happened that cause the helpers approaching too fast. A failure in the laser system could be a reason. The investigations will say. Maybe the train ahead reduced the speed too fast and the computer delay to recalculate the speed.

Date: 02/23/21 08:28 Re: Collision of the Vale helper locomotives (Brazil) Author: Rmosele Wow, that's amazing. So if there was an engineer in the helper he must have felt pretty helpless at the point where he realized the locomotives weren't slowing down. I spent a rainy week at that Vale mine near Carajas in 2003 observing operations while I was a vice president of the explosives company that they used. The mine and the railraod are amazing engineering accomplishments.

And congratulations on Video of The Day -- twice in a row! Thanks so much for sharing, Pedro! ~Joe P. Hainesville, IL |
