Introduction

In December 2023, the Rail Accident Investigation Branch (RAIB) released its report into an incident on the Elizabeth line near Paddington station on 27th January 2023. The report details the circumstances surrounding a collision between a passenger train and a stationary train.

The Incident

On 27th January 2023, a passenger train collided with a stationary train on the Elizabeth line. The incident occurred approximately 250 meters west of platform 14 at Paddington station. At the time of the collision, the passenger train was traveling at a speed of approximately 8 mph (13 km/h). The stationary train was at a standstill as its driver was preparing to depart from platform 14. The RAIB investigation found that the passenger train had passed a signal at danger.

Investigation Findings

The RAIB investigation revealed that the signal at danger was passed because the driver of the passenger train had not seen it. Contributing factors included reduced visibility due to sunlight, the driver’s task load, and the position of the signal. The investigation also considered the implications of the design of the Automatic Train Protection (ATP) system. The report details the sequence of events leading up to the collision, including the actions of both train drivers and the signaling system’s response.

Recommendations and Actions

The RAIB has made recommendations to Network Rail and Transport for London (TfL). These recommendations focus on improving signal sighting, reviewing driver training, and enhancing ATP system effectiveness. The report also highlights the need for improved communication protocols between train drivers and signallers. The investigation underscores the importance of stringent safety measures in railway operations to prevent future incidents. In response to the findings, actions have been initiated to address the identified safety deficiencies.

Elizabeth Line Trains

The report’s findings have implications for the ongoing operation of Elizabeth line trains. The recommendations aim to enhance the safety of the line’s services by improving operational practices and infrastructure. Implementation of the recommendations is expected to reduce the risk of similar incidents occurring in the future.

Conclusion

The RAIB report provides a detailed analysis of the collision near Paddington station, offering insights into the causes and contributing factors. The recommendations made are intended to improve railway safety and prevent similar occurrences.

Company Summary
