Service disruption Cambridge signalling problem

What's happening?

Network Rail engineers have now completed repairs related to an earlier signalling fault at Cambridge. This means that we can now run our trains via Cambridge as normal. However, due to congestion caused by the earlier line blockade, service disruption is expected until we restore our normal time table.
In the meantime, we have made arrangements for Greater Anglia tickets to be accepted on GTR services between Kings Cross and Cambridge.

Please note that GTR were also affected and some services may be subject to short-notice delays and alterations. Greater Anglia tickets can be used on London underground via reasonable routes. Please allow extra time for your journey.

GA Routes affected:

Ipswich to Cambridge

Liverpool Street to Cambridge North

Norwich to Stansted Airport
