We are delighted that the signs have been fully restored

The two heritage signs dating from the early 1930s are the only ones of their kind left in London and can be found on Maida Vale, part of Edgware Road.

They have undergone a thorough restoration process: sign cases have been reconstructed, existing panels have been replaced in original graphic style and poles have been treated and recoated in their initial colour.

Mayor of London, Ken Livingstone, said: 'These iconic London Underground (LU) heritage signs have been expertly restored so that they can continue to direct people to Maida Vale and Warwick Avenue stations for many more years.'

Mike Ashworth, LU Design and Heritage Manager said: 'We are delighted that the signs have been fully restored and are back on public display for all to admire.

'Not only do they serve a practical purpose in directing passengers to Maida Vale and Warwick Avenue stations, but they are fantastic examples of the Underground's rich design history.

'The Tube has many original heritage features which we are working hard to preserve, renew and restore over the next few years as part of the ongoing programme of works to Transform the Tube.'

The completion of the restoration process coincides with the Bakerloo line centenary celebrations taking place this year from March onward.

The Bakerloo line retains many of its heritage features, such as at Maida Vale station where there are examples of early Underground roundels in the station's foyer and a metal staircase balustrade with timber handrails.

At Kilburn Park, the station features bronze latticed windows and shop fronts while at Edgware Road the station building has an Edwardian red terra cotta façade adorned with spectacular mouldings.

Philip Davies, Planning and Development Director (South) at English Heritage, said: 'We are delighted that LU have restored these rare pieces of street furniture and reinstated the original Underground signs.

'They are an important part of the history of London's Underground and are a notable London landmark.'
