Write a story about getting stuck on a train

The subway suddenly stops. I groan in frustration. I have been waiting for months to go to this particular art exhibit that happens once a year and now I’m going to be late. I tap my foot out of impatience. Minutes pass by and the train becomes loud with angry passengers. 
          I slip away to the emptier part of the train. I need to call my friends stating I will be late. I search for my phone in my bag but I could not find it. I think I forgot it at home. I look around to see if I could borrow anyone's phone. I walk up to the person in the seat across from me.
                 “Excuse me is there any possible chance I could borrow your phone?” I question
                          “There's no use calling anyone down here. There’s no signal,” She responds
               “Thank you anyway,” I say and walk back to my seat in defeat. I look out the window to see that the conductor's part of the subway is gone. I start to panic, my mind looking at all the worst possible scenarios. Did anyone else notice? I sit in silence for a few minutes not knowing what will happen next.
                   “Where’s the conductor's car?” Someone yells out. The entire subway goes crazy. I continue to look out the window to block everyone out. I am lost in my daydreaming until I see a crack appear on the wall. I jump up. The crack begins to spread and spread. 
                     Water starts to pour out, suddenly I’m not the only one who noticed it anymore. Everyone is stunned. Clearly thinking of the same thing I’m thinking of. We are going to drown.
                   I watch in fear as the water is spreading more quickly and it soon covers the subway floor. I managed to hop on a chair in time but others weren't as lucky as me. 
                It begins to reach up to the chairs. The water seems to never stop pouring in. I then see another light, it’s firemen in a special train car. I am close to the exit door so I was one of the first ones evacuated.
