While the two are in the cubicle, his wife can be seen pacing up and down the train carriage, looking for her husband.
She tried to unlock the toilet as her husband raped the woman inside, but was unaware of what was happening. His victim gave evidence in court and said he took advantage of her at a time when she was drunk and helpless.
She said her life has not been the same since the attack and she was made to feel like it was "her own fault".
The woman has been struggling with PTSD, has panic attacks and cries uncontrollably during stress-induced fits.
Davies told the Canterbury Crown Court he was "embarrassed for cheating" on his wife.
According to KentOnline, he also said he had "no idea" why his victim wanted him locked up.
Since his arrest, he tried to accuse his victim of lying and suggested she initiated intercourse. However, he did not convince the jury, who unanimously convicted him of rape on Friday. Davies is an ex-manager of Margate's Durham House.
"[The victim's] life was turned upside down because of these five minutes inside the toilet cubicle," recorder Stuart Trimmer QC said.
"Not only did you do it, you called out to your wife outside, while [the victim] was being sick. While those words were being uttered you were having sex with the drunken woman."
