The British Transport Police currently has 155 authorised firearms officers. Their authority to carry firearms is derived from Section 58 of the Firearms Act 1968 as amended by Anti-Social Behaviour Crime and Policing Act 2014. There is no requirement for them to possess individual firearms certificates.
Prior to the amendment to the Act, officers were required to obtain personal firearms licences. During the period in question, BTP records show that 56 officers applied for and were granted relevant firearms licences.
