This is in the wrong place, I have asked the Mods to move it.
Railway land parking contraventions before 26/12/25 are not relevant land for transfer of liability to the keeper, and APCOA don't generally litigate, so it will probably go nowhere, but there's always a first.
But you could send a complaint to them to say you never received the original PCN and get them to send it. You can then send an appeal, as keeper only, on the basis of not relevant land so they can't hold you liable as keeper.
