How have I not found this yet? I've literally looked for a skip like this two times before lol, good find. Not sure how much faster the first one is to do rather than using the train, but it could either be a really good backup strat or it could just become the new strat.

the only reason i searched for this is because i found a similar skip to the first skip a while back with the door and the wall clip part of the fall plane but that was hard and i dont think its possible to do train skip here.
