Throughout nineteenth century railway rule books there is one regulation they will always certainly contain; that an individual being found 'under the influence' on the job will be dismissed. Far less common are regulations relating to what staff should do if a passenger is found drunk. I was, therefore, interested to find this one from the Barry Railway's rule book of 1889:
"247: In the event of any passenger being Drunk and Disorderly, to the annoyance of others, the Guard is to use all gentle means to stop the nuisance; failing which he must, for the safety and convenience of all, remove the offender from the train at the first station. The Guard must obtain the name and address of the offender , and also of one, at least, of the Passengers present at the time; he must also take care that the offender's luggage is put out of the train before it proceeds on its journey."
