According to Luis Gomez-Agustina, who teaches an acoustic course at London Southbank University, “the fact that most of the [London] Underground stations' surface materials are acoustically hard – [they are] highly reflective, they do not absorb sound – facilitates the noise generated to stay within the space for ...
The Waterloo and City line won the title of the safest line was followed by the London overground with 24, Docklands railway at 92, the Metropolitan line with 166 and the Hammersmith and City line with 364 thefts.
The Victoria Line is teeming with bacteria, having the highest number of germs of all the Tube lines. Touching your face after coming into contact with dirty seats and handles can transfer a whole host of blemish-causing bacteria.
Not including the Elizabeth line, which technically is not a standard Tube line, the line which is the fastest therefore is the Metropolitan Line. It is the fastest line on average across London but also has the fastest stretch of line - where trains can reach that magic speed of 60mph.
The Central line is a London Underground line that runs through central London, from Epping, Essex, in the north-east to Ealing Broadway and West Ruislip in west London. Printed in red on the Tube map, the line serves 49 stations over 46 miles (74 km), making it the longest line on the Underground.

Areas close to the M25 motorway showed the highest levels of noise pollution. And traffic-dense areas like Soho, Covent Garden and Westminster also recorded pretty high noise levels of around 70dB, which is about the same noise level as a washing machine. Unsurprisingly, places around parks were the quietest.
About half of the underground lines, in terms of length, are actually on the surface when out of the central area. It is easier and safer to dig at depth in London because of the nature of the soil and to avoid other infrastructure and the Thames.
London contains many other secret tunnels, including government passages beneath Whitehall, deep-level tube shelters and communications and utility tunnels.
