Network Rail has completed major work to improve the drainage at Potters Bar station to reduce the risk of flooding to the subway.
The project cost £300,000 and is part of the Railway Upgrade Plan.
Old pieces of track were removed and new pieces installed, which will better protect the subway from stress and vibration caused by passing trains.
The drainage was also cleared and a new system was installed and work took place to waterproof the subway.
In recent months, there have been several instances of flooding at the station.
During this time, Network Rail has carried out interim measures, such as drainage inspections to minimise the risk of flooding, but this work will hopefully provide a more permanent fix.
Johanna Priestley, route asset manager for Network Rail, said: “We know that in recent months, there have been instances of flooding in the subway at Potters Bar station, which has caused inconvenience for those using the station.
“This isn’t the experience which we want passengers to have and we’d like to apologise for that.
“The work we have completed at Potters Bar will reduce the risk of the subway flooding, creating a much more pleasant experience for those using the station and providing access to the station which is fit for purpose.
“We’ve worked closely with Great Northern on this work and we look forward to station users seeing the benefit.”
Great Northern’s Station Manager James Gillett said: “We are delighted that our Network Rail colleagues have been able to complete the track drain repair over the weekend.
“For the sake of our passengers and staff, we hope this flooding problem will now be a thing of the past.”
