TfL has announced an increase in services on the East London Line that is almost useful if you live in Brockley. From December 2011, trains on several routes across the London Overground network will run more frequently at peak times, evenings and weekends. Scheduled improvements include:
Two extra morning peak trains from Surrey Quays to Dalston Junction, Monday to Saturday
Four extra trains will run every hour between Dalston Junction and Highbury & Islington on Sunday mornings
The extra trains from Surrey Quays should make northbound journeys slightly less squashed for us from that point on, and it's encouraging to see them trying to squeeze more capacity out of the network this way. Perhaps more late night trains are not too far away.
