Well I have a really stupid but very fun idea in my head... I want to jump over a train, now I've never done this before so I don't know what the proper safety procautions are (if there are any).
If anyone out there has done this before let me know what you did so that maybe I'll live, and not die in front of my girlfriend.
I'd recommend making sure you know the height of ALL the trains that use the track. and what the other guy said.
Ya the plan is I'm going to build it then jump it with no train, film it and film a train going by from the dame angle and see if I'm getting enought air
