East London Line Extension to open on Monday

According to London Reconnections the East London line extension to Highbury and Islington will open on Monday 28th February - the first train will run at 0955. As that's one of my childcare days I can't be there, which is a pity. The extended route should increase usage of the ELL, which I have found to be pretty low outside the rush hours, now that it connects with the Victoria and North London lines.
