Same issue. The grates have fallen every time. I always end dropping and falling through the train. I then get to experience jumping around enjoy all kinds of clipping issues before falling through the train to my demise. . Any chance you plan on addressing this in the lifetime of the game? Haven't experienced this level of frustration since Descent into Undermountain.
I was having this issue as well. Yesterday I tried moving back to my left along the bar to barely be under the farthest panel. Then I was able to jump up and move past this damn clipping bug.
Please try that and see if it helps you too. I've FINALLY moved off of bracca!
