The Marquess of Ailesbury

asked Her Majesty's Government:

How the incidence of graffiti on London Underground trains is measured.

Lord Mackay of Ardbrecknish

The British Transport Police maintain a central record of offences involving graffiti on London Underground trains. In addition, the presence of graffiti is logged in detail at the relevant local depot before a train is removed for cleaning.
