High NO2 concentrations (long term average of 383 µg/m3
in 2016/2017) recorded at
Birmingham New Street railway station have resulted in the upgrade of the bi-directional fan system
to aid wind dispersion within the enclosed platform environment. This paper attempts to examine
how successful this intervention has been in improving air quality for both passengers and workers
within the station. New air pollution data in 2020 has enabled comparisons to the 2016/2017
monitoring campaign revealing a 23–42% decrease in measured NO2 concentrations. The new levels
of NO2 are below the Occupational Health standards but still well above the EU Public Health
Standards. This reduction, together with a substantial decrease (up to 81%) in measured Particulate
Matter (PM) concentrations, can most likely be attributed to the new fan system effectiveness. Carbon
Monoxide levels were well below Occupational and Public Health Standards at all times. The COVID19 pandemic “initial lockdown” period has also allowed an insight into the resultant air quality at
lower rail-traffic intensities, which produced a further reduction in air pollutants, to roughly half
the pre-lockdown concentrations. This study shows the scope of improvement that can be achieved
through an engineering solution implemented to improve the ventilation system of an enclosed
railway station. Further reduction in air pollution would require additional approaches, such as
the removal of diesel engine exhaust emissions via the adoption of electric or diesel-electric hybrid
powered services. [-]
