Thank you very much everyone for the feedback. I’ve revised the original copy to this below. Any further feedback would be greatly appreciated.
As previously stated, whilst I appreciate that I did inadvertently start my journey at an intermediate station when not entitled to do so, the correct course of action in such circumstances would have been to issue an excess fare. The price for this will be the difference between the amount paid for the Ticket l held and the lowest price Ticket available for immediate travel that would have entitled me to start my journey at the station concerned.
This is clearly stated in "The "National Rail Conditions of Travel", which states on page 9 9.5.3 "Where you break your journey when you are not permitted to do so; you
will be charged the difference between the fare that you have paid and the lowest price Ticket that is valid for the train you are using." and page 13, 16.3: "If you start, break or resume your journey at an intermediate station where you are not entitled to do so, you
will be liable to pay an excess fare. The price for this will be the difference between the amount paid for the Ticket you hold and the lowest price Ticket available for immediate travel that would have entitled you to start, break or resume your journey at the station concerned."
Paragraph 6 of said "The National Rail Conditions of Travel", also states "Please note that neither a Train Company’s staff, nor a Licensed Retailer’s staff has the authority to waive or change the Conditions unless they are specifically allowed to do so within the Conditions." and no such authority is given within The National Rail Conditions of Travel to change conditions 9.5.3 and/or 16.3.
Whilst the information box at the start of paragraph 16 does state: “INFORMATION: Most Tickets allow you to break your journey. This means that you do not have to make the whole of your journey at the same time or, where allowed, on the same day. Please note that “advance” Tickets do not permit a break of journey. The special conditions for “advance” Tickets can be found at
www.nationalrail.co.uk/advancetickets. Other national Ticket types normally allow break of journey with the exception of the outward portion of some longer distance “off-peak” returns. Where this is the case, it is made clear in the restrictions applying to those Tickets.”
Nowhere does it state that "advanced tickets" will be treated any differently to any other ticket that does not entitle you to start, break or resume your journey at the intermediate station concerned and again, no authority is given for a train company's staff to change these terms.
If it is disputed that The National Rail Conditions of Travel can be read differently, then section 69 of the Consumer Rights Act would be invoked: "Contract terms that may have different meanings (1) If a term in a consumer contract, or a consumer notice, could have different meanings, the meaning that is most favourable to the consumer is to prevail.
I trust you will now cancel the penalty fare as issuing a penalty fare notice in such circumstances is clearly in breach of "The National Rail Conditions of Travel" and the Consumer Rights Act and issue an excess fare as the correct sanction.
