In the 2022-23 financial year, the Rail Accident Investigation Branch (RAIB) did not pay for any formal equality and diversity training. In 2022-2023, RAIB did pay for two separate external speakers to raise staff awareness of disability and hearing loss, costing £200 and £250, respectively. The purpose of these talks was to support RAIB officials in the course of their investigations when dealing with the public and rail industry, as RAIB have had deployments and investigations where disability is a factor.
