§ The Marquess of Ailesburyasked Her Majesty's Government:
How the estimated cost of effectively protecting London Underground trains from extensive graffiti compares with the actual cost of removing them.
§ The Parliamentary Under-Secretary of State, Department of Transport (Lord Brabazon of Tara)London Underground Ltd. estimate that the cost of clearing graffiti from trains and stations in 1987–88 will amount to about £¾ million. Costs of effective prevention cannot yet be established. However, a range of security measures to protect trains in sidings are currently being tested in two pilot projects and some of these seem likely to prove cost effective in wider application. London Underground Ltd. are also experimenting with protective coatings and graffiti resistant materials.
