The middle makes more sense now.
Instead of a drop down only accessible by riding the train or using any kind of boost (rocket, sticky, flare, building etc...) has now been turned into a walkable hanging area with a transparent security fence.
There is now only 1 train in middle instead of 2.
Warning lights for trains have been littered around the tracks and the warning bell now plays everywhere
Added a custom sign to the door that only opens when the train passes for clarification (it's not broken guys)
Added teleport clips to the trains.
(as a result removed the killing barbed wire at the end of the track)
Added a lot of arrows, some that come out of the ground when middle is capped.
