The Government have not made any representations to Transport for London or BAA on this matter.
The escalators at Heathrow Terminals 1-2-3 Underground station are the responsibility of London Underground and are currently being refurbished to ensure continued reliability and to reduce the risk of failure in future. Responsibility for London Underground was transferred from the department to the Mayor of London and Transport for London in 2003.
The project is being carried out in phases with two out of the four escalators, which connect the ticket -hall and platforms, being worked on at a time.
The work on the first two escalators began in April 2009 and is due to finish in late August 2009. Work on the other two escalators will take place in 2010.
During the work, special one-way systems have been introduced to ease congestion and to keep disruption to a minimum—allowing the station to remain open while the work is carried out.
