Bailable offence and it's effect in future

Respected sir / Mam It's a kind request if u are reading this kindly reply since I am going through a great mental stress Recently some days back I was traveling in a local train and when I reached my destinated station RPF caught me ... only then I knew I was traveling in a ladies special train ( while boarding I couldn't understand because there were other male passengers as well ) I was produced before the railway magistrate and was fined Rs 700 and only then I was released ( I was detained for some 1/2 hour) After my release when I asked the bail paper they told nothing is required since the case is closed and I don't have to worry But still I have two question Will they keep my record or it will be deleted And my second question during my job will I have to mention ( if it's govt) ..will it anyway affect my career Respected sir / Mam do answer my questions after reading what situation I gone through ..I faced punishment without doing anything intentionally Thank you in anticipation
