Critics opposed to plans to shut a Tube station for eight months have launched a campaign to keep it open.
About 20,000 commuters daily use the station according to TfL
Transport for London announced plans last month to close Shepherd's Bush on the Central Line for improvement works linked to a new £1.6bn shopping centre.
The Westfield complex is due to open in late 2008 and developers think 60% of visitors will come by public transport.
But critics say the closure puts shoppers' needs before those of local residents and businesses.
"This is completely unnecessary," said Andy Slaughter, Labour MP for Ealing, Acton and Shepherd's Bush.
"It's a major station and no other station of this size has been closed for so long for improvement works.
"20,000 people a day and hundreds of local businesses rely on it and Transport for London are closing simply because they've been told to property developers."
Jamie Bishop, manager of the gourmet pie shop Jumbucks, said the planned closures threaten his livelihood.
"We're pretty upset," he said. "Last year we had to survive three months without buses because of works and now to have this is just unbelievable.
"How are we going to survive? We rely on the Tube and to close it is going to kill this part of Shepherd's Bush."
But TfL said the works were vital to replace old escalators ahead of a doubling in the number of passenger numbers.
"This is not about Westfield dictating to us," he said.
"We think this is the right decision for customers and for Londoners."
