TfL is consulting on two options for Crossrail 2, and the consultation closes on 2nd August. 

While I agree Hackney needs a tube line it seems these proposals are more concerned with future central area tube congestion than the transport needs of Hackney; the Metro option will have only one station in the borough, while the Regional option would see two.  The safeguarded Hackney-Chelsea  route with a third station at Homerton, has been dropped, mainly because relieving congestion on the Victoria and Piccadilly lines is seen as more of a priority. 

I'd like to see an analysis of the impact on Hackney, options with more stations in the borough, and a commitment to upgrade the West Anglia lines (seven stations in the borough) first.
