What would make you feel safer riding the subway?

I missed my stop on the G tonight so I got off the train one stop later and quickly noticed that a guy who was in the same car had also gotten off and was standing closely behind me on the mostly empty platform. I called my boyfriend and walked away slowly, but the guy followed me all the way down the platform. He kept lurking behind the pillars and angrily staring at me. There was only one way out of the station which required me to walk by this guy so I asked a stranger to walk me to the stairs and he did (thank you, kind stranger!). I ubered home but I am so shaken up by this experience and also really fucking angry. Why can't we as women feel safe doing ANYTHING? Are we just supposed to accept this as normal? It got me thinking, what would make you feel safer riding the train? For me, having designated women-only cars would go a long way. Curious to hear other ideas, no matter how big / small / realistic. Something has to change. Stay safe out there ❤️
