Where Is My Train Going?

The Matawan train arrived today at Newark with signage saying it was heading north to Hoboken. Yesterday it was marked as a Dover train and it arrived on a track marked for a Trenton train. This would be funny if it werent so dangerous. If computers are running our lives, I want NJT computers to know where my train is going, at least roughly. A week ago my Long Branch train arrived as a Trenton train. What's up? I hope the NTSB is looking into this.
