The Southall Rail Accident Inquiry examined the 19 September 1997 collision between a Great Western high-speed train and a freight train at Southall, which resulted in seven deaths and 139 injuries. Professor John Uff QC's inquiry found that the train's Automatic Warning System had been switched off and the Automatic Train Protection system, though fitted, was not operational. The inquiry made 17 recommendations addressing driver training, automatic train protection, and safety management systems.

The inquiry's findings contributed to significant railway safety reforms documented in subsequent legislation and institutional changes. The Railways (Safety Case) Regulations 2000 incorporated strengthened safety requirements informed by Southall's findings. The inquiry's examination of train protection system failures directly influenced the accelerated rollout of the Train Protection and Warning System across the UK rail network.

Southall formed part of a trilogy of major rail accident inquiries alongside Hidden (Clapham Junction, 1988) and Cullen (Ladbroke Grove, 1999). Together, these inquiries informed the establishment of the Rail Accident Investigation Branch through the Railways Act 2005, creating an independent body for investigating rail accidents. The failure to have Automatic Train Protection operational at Southall became particularly significant following the Ladbroke Grove collision two years later, where similar issues arose.

The inquiry's recommendations on driver training, AWS fault reporting, and safety management procedures were incorporated into revised Railway Group Standards. However, published evidence suggests that some recommendations, particularly those concerning vehicle crashworthiness reviews and post-incident liaison arrangements, received less documented attention in subsequent reforms.
