He said: "Network Rail are cashing in on the improvements to Herne Hill in recent years.
They are just going to exclude a whole range of traders. These traders are absolutely key to the area and it would be devastating to Herne Hill to lose them." Dulwich and West Norwood MP Tessa Jowell called on Network Rail to guarantee that existing businesses would be able to move back in to the area after their shops are refurbished.
They are going to rip the heart out of this community - the greengrocer, the butcher and the bakery. The locals don't want it because these are their local shops." Similar proposals for the rail arches around nearby Brixton station have also been criticised, with traders claiming they will be financially crippled by rising rents.
Giles Gibson, chair of the Herne Hill Forum, said the latest redevelopment plans "had not come as a surprise" but were likely to have a "devastating" impact on the local area.
She said: "This is a part of my constituency that has risen above adversity because of the power of the traders.
Network Rail cannot just wade in and expect people to accept their plans - it is quite wrong."In a statement, a spokeswoman for Network Rail defended the plans, saying the rail authority was committed to maintaining the "character of the area".
