Train Travel & COVID-19: How Safe Are UK Railways?

Introduction

This article delves into a study conducted by the Rail Safety and Standards Board (RSSB) in the UK, assessing the risk of COVID-19 transmission on trains. The study aimed to quantify the risk of infection during train travel, considering factors such as passenger density, mask usage, and contact time. This is crucial for public health and the railway industry’s recovery following the pandemic’s impact on ridership. The research analyzed various train models under different scenarios, incorporating data from various sources to create a comprehensive risk assessment. The findings offer valuable insights into the safety of rail travel during a pandemic and the effectiveness of mitigation strategies like mask-wearing. Ultimately, the study seeks to address public concerns and reassure passengers about the safety of using trains, contributing to the restoration of passenger confidence and the economic viability of the railway system.

Risk Assessment Methodology

The RSSB employed a rigorous methodology to assess COVID-19 transmission risk on trains. The study used a simulation model based on three different train classes (Class 800, Class 350, and Class 387) representing a variety of rolling stock commonly used in the UK. The simulations covered the entire passenger journey, from waiting on the platform to boarding, travelling, and alighting. The model incorporated data from the Office of National Statistics (ONS) on infection rates and contact tracing data provided by train operator LNER. This allowed for the modelling of various transmission scenarios including asymptomatic, pre-symptomatic, and symptomatic individuals. Crucially, the model factored in contact time and distance between passengers to determine potential infection likelihoods.

Risk Quantification and Mitigation

The study’s findings indicated extremely low probabilities of contracting COVID-19 during a one-hour train journey. The risk was estimated at one in 11,068 journeys without face coverings and one in 19,765 journeys with face coverings. These figures were derived from a combination of epidemiological data and the simulated passenger movements within the train carriages. The lower risk associated with mask usage highlights the effectiveness of this simple mitigation measure in reducing transmission. The study emphasized that these risks are tolerable and significantly lower than risks associated with other modes of transportation. This data serves as a vital tool for reassuring the public and policymakers about the relatively low risk of COVID-19 transmission on trains.

Comparative Risk Analysis: Rail vs. Other Transport Modes

The RSSB’s analysis extended beyond the isolated assessment of rail travel. A comparative risk analysis was conducted to contextualize the findings within the broader transportation landscape. The study revealed that rail travel is significantly safer than other common modes of transport, such as cars, bicycles, and motorcycles. Compared to car travel, the study demonstrated that trains are 25 times safer per kilometer travelled. Similarly, bicycles and walking were found to be 403 and 456 times more dangerous, respectively, while motorcycles were 1620 times riskier. This comparative analysis underscores the inherent safety features of rail transport, even during a pandemic.

Conclusions

The RSSB’s comprehensive study provided a robust and data-driven assessment of COVID-19 transmission risk on trains in the UK. The findings, showing extremely low infection probabilities, particularly when face coverings are worn, offer strong evidence to support the safety of rail travel during a pandemic. The rigorous methodology, incorporating epidemiological data, passenger movement simulations across various train types, and risk mitigation factors, contributes to the reliability of the results. The comparative analysis against other modes of transportation further highlights the relative safety of rail travel. By quantifying the risk and demonstrating its comparability to other everyday risks, the study successfully addresses public concerns about train safety and contributes to building public confidence in rail travel. The results provide crucial information for policymakers, transport operators, and the public, informing decision-making related to public health and the sustainability of the rail industry. The emphasis on the effectiveness of simple mitigation strategies, such as face mask usage, also underscores the importance of public health measures in managing the risk of transmission in public transport settings. The study’s recommendations regarding public education and risk communication are essential for encouraging greater utilization of public transport and fostering a safe and efficient rail network. Ultimately, the RSSB’s work reinforces the role of scientific evidence in informing public policy and building trust in critical public services.
