 The Commission will respond to the proposal in the first half of 2009.As for the existing Beaulieu pole, which is to the south east of the main European quarter, there is a proposal to link it with the main quarter by covering the railway lines between Beaulieu and the European Parliament (the esplanade of which sits on top of the Brussels-Luxembourg railway station).Traffic on the lines is expected to increase creating environmental problems that would be solved by covering the lines.
