If you are thinking of travelling to Kent by train tomorrow, you might be intrested to know that there are railworks on both lines in Kent tomorrow, meaning that no trains are leaving Charing Cross and the ones from Victoria are stopping short either at Meopham or Strood with an ongoing bus service. The delays are not insurmountable but could be a problem for someone travelling to the match from your distance.
This link may help you, showing the work as it is:
