Same video as the other one, just re-posted. I still can't quite figure out why the track washed out like that, though.
Edit: Per the link below, the washout was in Stackpool, Ontario on a CN line. The video here is also a bit longer...seems there was a stream running either right by the track or right under it that undermined the soil. The extra minute makes it a bit more apparent that there's a decent-sized stream running under the tracks after the washout, though I still can't quite tell what the cause of the washout was (aside from water being annoying).
