Passengers in Huntingdon and St Neots have been affected today, with many services heading towards London cancelled. It follows a power line failure yesterday. A spokesman from First Capital Connect (FCC) said work would be carried out overnight but admitted getting the service back on track would be a challenge, because trains and crews may need to be shifted. He said: Network Rail say that they anticipate finishing the work early tomorrow morning. If they are completely repaired, that line will be back open. Whether were able to run a normal service depends on where weve got trains and where weve got crews. A revised timetable for this evening has been drawn up and trains are leaving Kings Cross to Peterborough twice an hour - at six and 36 minutes past the hour. Trains travelling from Peterborough to Kings Cross depart at 16 and 46 minutes past the hour.
