The filthiest London Underground lines have been identified and the worst ones are only cleaned every 43 days.

According to a recent Freedom of Information request, it has been revealed that the Piccadilly line is the dirtiest tube line in London. This finding may come as a shock to some, but it serves as a reminder to always wash your hands after using the Underground. Showers to You, the organization that submitted the request, discovered that Piccadilly line trains are only given a full-service clean once every 43 days.

The Piccadilly line has a fleet of 86 trains, making it the third largest among all of the Underground lines. However, despite this relatively large number, the line still falls behind in terms of cleanliness. In fact, the Jubilee line, with a fleet of only 63 trains, is considered the cleanest of all the lines, receiving a full-service clean every 18 days.

It's worth noting that Transport for London (TfL) has a detailed and specific cleaning schedule for all tube trains. This includes a daily pre-service clean, as well as additional cleans every three to four days, which involves cleaning of window ledges, windows, and interior panels. Every four weeks, the trains on each line undergo a full interior and exterior clean.

A spokesperson for TfL explained, "Our cleaning schedule for Tube trains consists of three different levels of cleaning: pre-service cleans, further cleans every 3-4 days, and a full clean of the interior and exterior of the train every 28 days." This level of detail and frequency shows the commitment of TfL to maintaining a high level of cleanliness on the Underground.

The FOI also revealed that the Central line trains are cleaned every 27 days, while Bakerloo line and Northern line trains are cleaned every 25 days. The Metropolitan, Hammersmith and City, Circle, and District lines are cleaned every 28 days. These findings may come as a surprise to some, but they serve as a reminder of the behind-the-scenes efforts to keep the Tube clean and safe for all passengers.
