Phil Jones, who works as a crime reduction manager for Northern, was commended for stopping a suspect who had attacked a conductor on a train service in West Yorkshire.
He detained the man at Wakefield Westgate when the train stopped at the station.
The incident involving Jones happened in September 2019, but he has only just been formally recognised because the awards were suspended during the pandemic.

He was among five employees at Northern to be awarded a Certificate of Commendation at the British Transport Police Pennine Sub Divisional Awards.
Jones’ colleagues also picking up commendations included conductor Lorna Brown and driver David Greenslade who stepped in to break-up a fight of approximately 20 males at South Elmsall in May 2021.
