G'day everyone, I'm curious to know whether all four lines between Camden Road East Junction and Dalston Kingsland are all currently in use. I only ask because when I traveled along the route yesterday a sleeper was placed across one of the lines between Camden and I think Caledonian Road and there seemed to be a lot of weeds about for what I assume is a running line. Also, when we arrived at West Hampstead station we were told that there were significant delays on the line to Stratford due to a broken down train but saw nothing and suffered no disruption. This was all at around 11.00. Any ideas? Kind regards, Richmond Commuter!
