I worked on the railways and to start with when I was a conductor checking tickets I would not bother with a single woman in a compartment on her own for that very reason. Not that women have willies, although times have now changed, I mean the potential for an accusation. I wouldn't even bother with any females alone or in a small group unless there were other passengers around.
Another conductor I knew asked to see the tickets of two young ladies in a single compartment. They had no money and no tickets. As the next stop was a main line station, London Victoria, he called ahead for the British Transport Police to meet the train, which they did. The two young ladies then said the conductor was lurid and had propositioned them in exchange for free travel which they refused.
A rule on the railways said to me often by other train crew when first employed, they will always believe the accuser and not the accused so be careful.
Between the time of the accusations and it going to court before the case was dropped over a year later, by the CPS, he'd lost his job and his marriage broke up mainly due to the stress. The girls eventually admitted they had lied. No action was taken against them. This conductor had worked as a conductor on the railways for over 30 years. He won his industrial tribunal but at what cost? He had at the time been married for around 35 years. I saw him a few years later and he was a broken man aged 60 plus living in one room in a shared house. He had done nothing wrong except not being wise enough to be careful and intelligent. He had trusted the system he was working on behalf of to protect him. Fool, albeit an innocent fool.
