if you take a really harsh bail, then that is the worst that can happen, so go at it and just commit, there are sometimes where you do everything right and you just catch an edge on the rail, make sure the rail is not garbage also, becuse you can be more prone to catch and edge which is not a good thing.
turn the full 90, and don't go from the side, go right at the rail or go at the side where you have to pop over the rail to get on, that way you fully commit.
