Crashed my Car

Well, now just before you freak out. No one in my car was hurt. Don't know about the other car because it took off, but everyone in my vehicle was ok. It was just me and my niece Kajsa in the car. We were going to pick up Dionte from the gym cause it was raining but decided to go down past the temple down Collins Road way to Melville because it would cut all the traffic out. On the way, before we got to the railway lines, we were following a car with a trailer on the back. Now it was still day time but raining so the roads were slick anyways. We were getting closer to the railway lines and had slowed down a bit. Then the lights on the railway lines starrted flashing. And the car in front of us just stopped out of nowhere. You couldnt see any back lights on and you couldnt tell it was stopping until it had stopped. There was no where for me to go but rear end this car. My car ended up pushing the car onto the railway tracks so they speed up and went onto the other side of tracks and this all happened before the gates had even come down. The train came, I checked to make sure that Kajsa was ok and hopped out of the car to inspect the damage. The bonnet was bent up, one light smashed, one had popped out, the front of the car had been pushed inwards. I turned around to see where the other was, and they had already started driving. I didnt even get the licence plate or anything. Just a kinda description of the car. Drove to my brothers house to call the police and report the accident. Rang around and told the family what had happened. Checked again to make sure Kajsa was ok. I was soo ticked off that this happened right before Christmas. I take responsibility for me not stopping sooner, funny thing was, i had my eyes on the car in front of me the entire time, i wasnt tailgating, speeding or anything. But i still couldnt gage that they hadnt stopped until it was too late. So now, its waiwai express all the way.
