Is it really that strict?
A single prosecution under strict liability for something that is plausibly a genuine error?
Passengers can be prosecuted when there is no intention of attempting to avoid the fare; there is a thread discussing this topic at:
I was on a train this week which had two RPIs and one security officer board. In my carriage there were the following two people caught right near me, both of whom were given a simple penalty fare 1) No ticket with no attempt at an excuse as to why one was not purchased 2) Attempting to flash...

Passengers have been prosecuted when the passenger did nothing wrong, for example:
I'm really hoping there are some experts on here who can explain things for me. My daughter travelled from Brookman's Park to King's Cross having bought a return ticket and adding in the travelcard option from the machine at Brookman's Park. On her return journey later that day she got a text...

(This is a particularly good example as it did actually proceed to court; the train company lost the case and had to compensate the defendant)
This would end someone's career?
Below is a thread where an example was posted (post #30) of a non-recordable Byelaw offence became a big deal:
People may be interest to see, and have observations upon, the following to Met Police Misconduct Hearings related to discounted risk travel. It would be interesting to hear any observations re the TOC evidence in each case. Seems to be a bit of a spate of these. Misconduct (gross misconduct...

Sometimes there is sufficient evidence to demonstrate intent to avoid the fare, but train companies can avoid any requirement to demonstrate that intent, by prosecuting under the Byelaws instead of more appropriate legislation for the actual offence committed.
For someone to be guilty of a byelaw offence, they do not have to be attempting to avoid the fare and this absolutely can be down to a mistake (on the part of the customer, or even railway staff!) or being a victim of crime or misinformation.
But all of the above is best discussed in the relevant threads, rather than this one; hopefully you will find the links insightful.
