There is disruption at Liverpool Street this morning due to signalling problems. I'm trying to get to Southend. Myself and other passengers were advised to travel to Shenfield and connect from there, only to find no service immediately available there either. The staff at Shenfield have gone out of their way to keep passengers informed, regularly coming onto the platform to resolve queries and regularly giving live updates on how far the next train was from the station. They were exceptionally helpful.
