If I was a passenger then the second I decide that I wish to alight and then step off the train onto an unlit platform then I must accept that I have placed myself into a situation where it may be unsafe and due to it being dark I would need to take care. It is still your choice to alight.
That wouldn't fly had there been serious injury. Not even slightly.
Where were the unsafe environmental warning signs or announcements?
Do the terms and conditions of carriage clearly state that an unsafe environment is provided as a default at all times unless otherwise advised?
Since when was it to be assumed that alighting at a planned station stop is unsafe unless otherwise advised?
If the passenger, sorry paying customer, had stayed on the train, who's responsibility would it have been to get him home from a distant station? Would the person on the ground have accepted the previously unsafe station and called a taxi funded by the TOC?
Might it have been even less safe at 1.30am on an unfamiliar station?
From the passenger's point of view (a bit radical around here, I know

), might it have been reasonable to assume that the next station might not have lighting too?
I think we all know the answers that would apply in the majority of occurrences.....
Starmill - well done for bringing it to the TOC's attention even though, according to a significant part of this thread, the fault is actually yours and yours alone. Obviously. :roll: The opinion-gathering to support this assertion will no doubt continue.
Whatever the opposite of "the customer is always right" is (which I don't subscribe to) it clearly applies here. We (the customers) are clearly inattentive, inconvenient and unintelligent halfwits because all of the bright members of the human race work for the railways.
Please let us know the TOC response.
