Odd video of CN locomotive running over trees
Posted by longhorn1969 on Thursday, May 17, 2018 8:43 AM


Entertaining to watch and definately a "physics" lesson, but isnt' there some possibility of damage to the traction motors?

Do you think the plow or front guardrail would be damaged too?

Yes there is the potential for traction motor damgae - there is also the potential for traction motor damage at poorly maintained highway crossings.

Traction motors are constructed to be rather robust pieces of machienry and have been designed  to 'shrug off' minor impacts such as the trees that were run over would present.  The bigger potential in running over the trees is for them to become entangled and break a air hose coupling somewhere back in the train.

The pilot structures of diesel locomotives are also robust and are designed for for such impacts and in many cases will shove the impacted trees out of the gauge of the track.

There you go!  Show those trees who's boss!

Seriously though, it seems to me that by the time the crew sees them it's too late to try and stop anyway.  Might as well keep on goin'.

The locomotive appears to be a ES44DC, and most of CN's have the angle cock behind the steps and underneath the cab, away from the impact zone.  

834 is grain empties, and normally has more than one unit.  Even if the lead unit were to lose power due to traction motor damage there would most likely still be enough power available to get the train over the road.  

Agree about the tendency for the plow/pilot to break up trees into little pieces (steel beats wood), but my main concern in this sort of situation would be if a larger tree were to directly impact the windshield and shatter it.  

This sort of situation is a common occurrence in the Pacific Northwest, with heavy, wet snow weighing down trees.  Nothing new, just caught on tape this time.

This footage is from the area between Blue River and Valemount, B.C.  I have worked that line and know the crew from this train.  As you can see they are fun people with a great sense of humour.

Sure is nice and quiet in the cab (except for the thumps).

I'd be more worried about the cab windows breaking from the impacts with some of those branches.  Sure, they're safety glazed and all that, but they'll still shatter if hit hard enough.

Thanks for posting that video - a definite 'cab ride' feel, nice scenery, and yes, it was entertaining!
