Trainee rail conductor rescues puppy on tracks mid-lesson

Stefan Hug brought the Southern train to a standstill to recover the uninjured dog

A puppy spotted on the tracks of a busy London railway has been rescued by a trainee who was in the middle of a train driving lesson.

Stefan Hug, from east London, only started learning to drive a train in January but was forced to stop a Southern service from Beckenham Junction to London Bridge on Wednesday morning after seeing the small black puppy running alongside the train.
