using the app called bubble (the good one, make sure its reading positive angle) you can check the angle of an urban rail to the tenth of a degree. I thought this was interesting and started checking different rails. seems like the older the setup the gnarlier, but ive found some really steep single rails that arent even handrails, more like guard rails for retaining walls. whats the steepest rail thats been done?
