Work is proceeding well to build the short stretch of new line to connect the ELL (East London Line) from Surrey Quays to the line that will run to Clapham Junction via Queens Rd Peckham, Peckham Rye, Denmark Hill, Clapham High St, Wandsworth Rd. Foundations are also being laid in the work for a new Surrey Canal Rd Station to be built later. This post from London Reconnections, 13 July 2011, has some interesting pictures of the construction work.
