Thank you, that is exactly my point. If you can operate the manual release, you don't need a pry bar. If you can't operate or reach the release for some reason, I'm not sure a small pry bar would help and a larger one is just too heavy to carry everyday unless you get a lightweight (and expensive) titanium one.

To me, opening train doors is not a practical reason to endure the inconvenience of carrying a pry bar in an EDC kit. Obviously, train doors are not the only situation a pry bar may be useful, though, but we have to choose the situations that we ultimately prepare for. I make sure to have a pry bar right next to my bedroom door in case a California earthquake shifts the house enough to jam the door
