Can you tell me more about the incident?

Following overnight works in the Portsmouth Harbour area, Network Rail need to carry out a controlled procedure to reset some parts of the signalling system. This can only be done by trains running in a specific order, and drivers will also need to gain verbal instructions before continuing.

As this takes extra time, there is some congestion.
