Transport for London (TfL) is currently engaged in an intense and ongoing battle to remove thousands of pieces of graffiti from the Central and Bakerloo lines of the London Underground, reflecting a significant resurgence of vandalism that has drawn growing concern from both the public and transport officials. TfL has disclosed that it is undertaking 24/7 cleaning operations to tackle an unprecedented volume of graffiti, averaging more than 2,000 tags weekly on the Central line and over 1,000 on the Bakerloo line. This surge in vandalism has resulted in about 23,000 pieces being removed in just two months, which equates to roughly one piece every eleven minutes.

The rise in graffiti is being attributed to several complicating factors. One primary issue is the shortage of available trains for cleaning, stemming from both the aging nature of the fleets on these lines and ongoing upgrade programmes, particularly impacting the Central line. This scarcity of rolling stock means trains often cannot be withdrawn from service promptly after being vandalised without causing disruptions during peak hours—resulting in dirty or graffiti-covered carriages remaining in use. Additionally, the lack of onboard CCTV on both the Central and Bakerloo lines has made them more vulnerable targets for vandals, further complicating law enforcement efforts.

TfL officials have emphasized the scale and difficulty of the cleaning task, with the Intensive efforts featuring teams who employ a combination of powerful cleaning fluids—akin to paint strippers, but fire-resistant for tunnel safety—manual scrubbing, and power tools to strip away the extensive tagging. Cleaning a single tag can take anywhere from five minutes to over an hour, with teams sometimes facing over eight carriages per shift. The cleaning operation is physically demanding, especially amid the summer heat, requiring protective clothing and masks. About half of the Central line fleet has been cleaned to date, but the process is ongoing and resource-intensive.

The motivations behind these graffiti campaigns appear to be fuelled by an online graffiti subculture that sets challenges or "prizes" for tagging specific targets, including new train fleets. For instance, the new Piccadilly line trains were subjected to such attacks during transport from Austria to London. Vandals are described as a tight-knit and motivated community, who often carry out graffiti during passenger service hours, brazenly tagging train exteriors and interiors despite surveillance and security patrols. TfL has noted that these attacks often occur late at night and in less monitored siding areas, with graffiti artists typically using disguises such as baseball caps and face coverings, making identification difficult.

Attempts to counter the problem include not only the around-the-clock cleaning but also collaboration with British Transport Police to apprehend vandals. However, besides the immediate cleaning logistics, the wider challenge is one of capacity and infrastructure; the older fleets need replacement and upgrades to improve service reliability and allow effective removal and maintenance schedules without negatively impacting passengers.

TfL has stated that it is seeking investment to replace and upgrade trains to provide a higher quality transport network that meets Londoners' expectations. Officials also stressed that promptly removing graffiti is essential to prevent a snowball effect of more vandalism, which would otherwise damage the Tube’s brand and the public’s sense of safety. Maintaining clean trains is viewed as a crucial factor in deterring not only graffiti but other criminal activities.

In the meantime, TfL faces what has been likened to an endless task, reminiscent of the "mythical endless repainting of the Forth Rail Bridge," with thousands of graffiti pieces and repeat offences making it a continuous and exhausting fight. Public sentiment echoes the frustration, with many calling for stricter penalties and stronger enforcement to protect public spaces from repeated vandalism.
