Is there anything the driver can do please?
You said the Keeper (the person who has received the Parking Charge Notice (PCN) issued as a postal Notice to Keeper (NtK) was not the driver. The PCN is not addressed to the driver so they cannot do anything. Even if they wanted to, the driver must to NOTHING!!!!!!
They have no idea who the driver is unless you, the Keeper blabs their identity to them. Why on earth would you want to do that when there is no legal obligation for you to do so. Only the
unknown (to them) driver can be liable. All the Keeper has to do is appeal with the following:
I am the registered keeper. UKCPS cannot hold a registered keeper liable for any alleged contravention on land that is under statutory control. As a matter of fact and law, UKCPS will be well aware that they cannot use the PoFA provisions because Leeds City Stattion is not 'relevant land'.
If the landowner wanted to hold owners or keepers liable under Railway Bylaws, that would be within the landowner's gift and another matter entirely. However, not only is that not pleaded, it is also not legally possible because UKCPS is not the station owner and your 'parking charge' is not and never attempts to be a penalty. It is created for UKCPS’s own profit (as opposed to a bylaws penalty that goes to the public purse) and UKCPS has relied on contract law allegations of breach against the driver only.
The registered keeper cannot be presumed or inferred to have been the driver, nor pursued under some twisted interpretation of the law of agency. Your NtK can only hold the driver liable. UKCPS have no hope should you be so stupid as to litigate, so you are urged to save us both a complete waste of time and cancel the PCN.
