Property Invasion, Damages, Trespass Defiant Trespass 2C:18-3b in New Jersey

[Helpplease]

I was walking toward the train station and the railroad gate came down behind me and the train pulled into the station. It stopped and I crossed the track (underneath the train car, I was too far from either end of the train to walk around) and got on the train. I got a ticket for defiant trespass 2C:18-3b. Can I fight this charge? If I lose what are the likely penalities? Will I have a criminal record?

 

[disagreeable]

You can fight the charge, however, it appears the legal response would have been to return to the appropriate side of the gate.
