On 9th April 2015
@thebigcheese was denied travel by Southeastern staff at St Pancras; they had objected to the use of the outward portion of his ticket earlier in the day and claimed the ticket had been "banned" in time for his return journey.
@thebigcheese was travelling in accordance with the itinerary provided as part of his booking, which is evidence of a contract.
Also
@Merseysider reported a similar refusal by Southeastern:
Three of us on valid tickets that SE's incompetent minions gateline attendants plus one supervisor/manager didn't want to accept as valid, even after two printed itineraries, the National Rail website, SE's Twitter team, the Southeastern website and SE's customer service via phone all confirming we should be allowed to travel, for anyone that wasn't there. Two of us bought new tickets and are in the process of deciding how to proceed.
On many occasions
@RJ was denied travel and/or removed from trains or incorrectly issued penalty/excess fares by Southeastern, who also committed a data breach in 2013:

@SETCommuter experienced being the victim of false allegations of committing crime when using a valid ticket; though it appears he was not charged or taken to court, it was an unpleasant experience:

In November 2012 Andrew Myers was denied travel using a valid Season ticket and was forced to purchase a new ticket; the matter went to court and the customer won the case:
https://www.railforums.co.uk/thread...r-of-passenger-using-a-permitted-route.90684/ however many people would not have been prepared to go to court and would have been left out of poicket. The TOC was First Capital Connect (FCC) which has since become part of Govia Thameslink Railway (GTR).
In 2013
@LuluG was issued a penalty fare by FCC for using a valid ticket that simply had the word "Disc" (short for discount) on the ticket; the ticket had an online discount applied

In 2011
@jon0844 was detained by an FCC RPI for three hours despite holding a valid ticket:
https://www.railforums.co.uk/threads/mg11d-by-my-favourite-fcc-rpi-combined-z123-z456-ticket.47857/ (last I knew, the RPI who did that was promoted to the role of Driver)
The issues on GTR with regard to brand names are very well documented; there are too many incidents to list them all, but the company has issued many penalty fares, new fares, excess fares to passengers holding perfectly valid fares, which GTR have claimed are invalid due to a brand restriction, for which there is absolutely no basis in the Ticketing Settlement Agreement (TSA) or any of the relevant legislation. This has been going on since the days of Southern (see
https://www.railforums.co.uk/threads/penalty-fare-at-victoria-southern-vs-gat-ex.117738/ and
https://www.railforums.co.uk/threads/southern-admit-they-were-wrong-to-sell-gx-supplement.64324/ ) which suggests the DfT may be in cahoots with the relevant train companies over this matter.
If you tap in to gain entry into Wimbledon station, then board a tram, you can be issued with a penalty fare or threatened with prosecution, as happened to
@Jaybee111:
https://www.railforums.co.uk/threads/tram-penalty.155758/ (OK so this may not be "valid" but a layperson may not unreasonably think they are valid)
A passenger was taken to court over holding a valid ticket routed +London on CrossCountry:
https://www.railforums.co.uk/threads/taken-to-court-facing-criminal-charges-advice-needed.156920/ ; the ticket was entirely valid for the journey made (equally by completing the double-back between Reading and London or also also by not doing so) and yet the passenger was prosecuted on the erroneous basis that the train did not go via London.
Another passenger was taken to court on the erroneous basis that the customer is responsible for their connecting train being delayed:
https://www.railforums.co.uk/thread...ion-sowerby-bridge-birmingham-journey.203895/ ; the customer should have been compensated, not prosecuted!
The above incidents are mostly historical because they occurred back to the days when I read every thread posted in this section. I no longer have time to read more than a tiny percentage of posts, partly because I am busier but also mostly because the forum has grown massively in that time (from 150 active members per day to around 3,800). I'm not the best person to recall recent incidents but there must be many of them.
I am also aware that
@MikeWh has assisted many people who have made legitimate journeys in the London area, particularly using Contactless/Oyster PAYG, who have tapped in & out correctly, and yet been issued penalty fares or threatened with prosecution.
