The graphic, created by Steven Bernard of the FT Data team, is based on &#8220;PM 2.5&#8221; air pollution particulate matter readings, measured by FT researchers while travelling in tube carriages between stations in an area roughly bounded by the circle of the Circle line. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It shows that the deep-level tube lines are worse for PM 2.5 than the &#8220;cut and cover&#8221; ones (which form the border circuit of the map here), but that pretty much everywhere in the zone has PM 2.5 readings above the WHO safe limit. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It also shows that once again, the Central line is the line that you really don&#8217;t want to be on (and that should have had many of its journey now replaced by the Elizabeth line &#8211; however that is now very late). Be it crime, temperature, overcrowding or pollution, the Central line always wins.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <a href=\"https:\/\/www.ft.com\/content\/6f381ad4-fef7-11e9-be59-e49b2a136b8d\">accompanying article<\/a> goes into detail about the measurement work, the nature of the dust, and how hard it is to clean. It&#8217;s surprising that only in the last 3 years has TfL started to think seriously about the pollution in the central London tube tunnels, some of which have been carrying passengers for more than a century. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>\u00a9FT.
