Public transportation might cause discomfort, especially for elderly people or people with other health issues.

The distinct metallic odor that fills the underground transportation system raises concerns about potential health hazards. The confined spaces and the strong smell can create discomfort and uncertainty for commuters. Additionally, the iconic red buses, while emblematic of the city, turn into baking ovens during the sweltering summer months due to the lack of air conditioning or at times proper ventilation. This discomfort can lead to unpleasant journeys and even impact people's well-being. These issues highlight the need for improved transportation conditions in the city, ensuring both the safety and comfort of its residents and visitors.

Thanks very much for posting this here, nice and specific. I believe it's true that the air quality is pretty bad underground. It's a good job we are not underground for that long - although I dread to think what the cumulative effects are if you commute underground every day for a whole career, as many do. Would welcome comments from any air quality specialists reading this please.

Thank you for your post D. Benny. That's well observed re: the metallic odour in the tube - I had vaguely noticed it in my journeys but I hadn't really taken it in.
I find rather difficult to ignore the high level of noise that some underground trains make moving along the tracks. I'm specifically thinking of a relatively recent line like the Jubilee. Does anyone know why and could this be considered noise pollution?
