I sent a woman to the station and said that when she got there, she would text me to tell me that she was safe. ...

It's no use worrying about this. Since you are out of town, the only contact way is your mobile phone. All you can do is wait for her to come back and ask her yourself, or wait for her to call and tell you what happened.

However, it seems that you are quite confident that you will catch up soon. It should be a trivial matter that the mobile phone is dead or stolen. Don't worry too much. I wish you early success.
