In the early evening of 8 August 1996, a Class 321 passenger train operated by Network SouthEast travelling from London Euston on the West Coast Main Line Down Slow line at around 110 km/h (68 mph) passed a signal at danger. Having applied the brakes it eventually stopped 203 m (222 yards) past the signal and was traversing the junction between the Down Slow line and the Up Fast line. An empty Class 321 coaching stock train approaching at roughly 80 km/h (50 mph) collided with the stationary passenger train approximately 700 m south of Watford Junction whilst progressing across the connections from the Up Slow line to the Up Fast line.
As a result of this accident, the train driver was charged with manslaughter by the Crown Prosecution Service on 10 January 1997, following an investigation by the British Transport Police. On 11 March 1998, the driver was acquitted at Luton Crown Court.
In its report, the Health and Safety Executive (HSE) advised that there was insufficient evidence to justify legal proceedings against the other involved parties, namely Railtrack and Network SouthEast.
Following delays caused by the criminal proceedings against the driver, the HSE and the Office of Rail Regulation jointly published its Report into the railway accident at Watford South Junction on 8 August 1996 on 29 April 1998, a summary version was published on the internet on 21 May 1998.
The HSE and ORR concluded in its incident report that there were a number of mitigating factors that contributed to the incident.
- The collision would have been avoided if the Automatic Train Protection (ATP) system had been fitted to the train and track.
- The inappropriate positioning of a speed restriction sign as a result of imprecise wording in the Railway Signalling Standard which gave confusing information to the driver of the passenger train.
- The signal passed at danger had a shorter than normal safety margin known as an 'overlap' intended to reduce risks from small misjudgements by train drivers or increased braking distances (e.g. as a result of wet leaves on the line).
