Peak time emissions from diesel trains at London’s Paddington Station far exceed European recommendations, a new study has found. With emissions within the station far higher than those on a nearby busy road, the results serve as a reminder that, despite a good track record, the railway sector could improve its performance even further.
Peak time emissions from diesel trains at London’s Paddington Station far exceed European recommendations, a new study has found. With emissions within the station far higher than those on a nearby busy road, the results serve as a reminder that, despite a good track record, the railway sector could improve its performance even further.
The researchers evaluated air quality in London Paddington train station over a period of five days and each time found it to be in breach of European limits regarding nitrogen dioxide (NO2) for outdoor air quality. Further comparisons sampling particulate matter (PM2.5), sulphur dioxide (SO2) and NO2 concentrations also found these to be much higher than on the busy Marylebone roadside located nearby.
Research found that ‘’enclosed railway stations hosting diesel trains pose a risk to passengers and workers ‘’ due to polluted air .
Globally, railway travel enjoys a positive track record, scoring as one of the greenest modes of transportation available. While the entire transport sector contributes about 22% of global emissions, rail only accounted for 0.8% of this between 1990 and 2009, statistics from the European Environment Agency (EEA) show.
New Reduction Standards and How To Achieve Them!
In December 2015, new reduction goals were outlined as part of the Low Carbon Sustainable Rail Transport Challenge, an initiative spearheaded by the International Union of Railways. The challenge aims for cutbacks of 50% in both energy consumption and CO2 emissions from train operations by 2030 relative to a 1990 baseline, and a total energy reduction of 60% by 2050. The best way to achieve these cutbacks has already been proven , “to retrofit existing locomotives with the Hydrogen on demand technology . Not only is it cost effective but it brings
all diesel trains with in pollution standards with Significant reductions of greenhouse gas emissions (CO,CO2,NOx,HC,SO2,NO,PM,VOC,CH4,SF6, and PFC).
As well as diesel fuel savings from 10-20 percent are achieved
