The British Transport Police is the national police for the railways in the U.K.. Every day they watch over the journeys of over 6,000,000 passengers, with the goal of getting them home, safe and sound.
The job of the BTP has been getting more and more difficult, with a higher influx of people taking trains across England, Scotland and Wales on a daily basis. In fact, in 2018/2019, there were 68,313 notifiable crimes. However there were only 60,867 in 2017/2018, so there was an increase of 12%.
There was one crime, however, that they probably could have skipped over.
