I may have missed connecting with a very hot girl?

I was heading for the metro. I saw an extremely beautiful blonde girl sitting near the entrance to the metro. She saw me and looked at me as I was walked past. I wish i had talked to her but I did not know how, and I was in a rush somewhere anyway. Interestingly, girls often hang around entrances to the metro and I was curious why. As for the girl I saw, if I wanted to connect with her, tell me what I could have done and how?
