In order to reduce signal failures we are replacing old track, improving drainage, cleaning block joints at regular intervals and improving the insulation between track sections using a new type of rail joint.

We are also upgrading signalling systems across the network. When London underground opened in 1863, the signalling was controlled at each station by signal boxes. These signal boxes directly controlled the signals and points in the area. New signalling systems computerise and centralise these boxes into control centres.
