 The reason for cancelling the contract to fit Cab Secure Radio to this line prior to the incident, as mandated in the wake of the previous Clapham disaster and Hidden report recommendations, remains unclear; however it seems likely that the changes occurring at the time, such as the channel tunnel and privatisation of the rail network, took priority over funding.Radio began to be installed across the railway immediately following the incident, and an inquiry was started.The accident was exacerbated by the age and design of the multiple units involved.
