ROOF leaks continued to plague Newport Station users almost three years after a £20 million revamp.

Rail bosses said the dripping was caused by "interface issues" between materials used during the building works but expect the roof to be leak free as remedial works have nearly reached their conclusion.

Matthew Evans, the Conservative group leader of Newport council, criticised Network Rail after being forced to dodge puddles of water at the station caused by downpours last weekend.

Cllr Evans, the former Newport City Council leader, said: "It's just embarrassing to go into a building and see buckets of water and rain coming down the platforms.

"It doesn't enhance the image of the city when you get a leaking roof.

"The Welsh Government invested millions of pounds into it. It's something that needs to be resolved."

Network Rail could not say how much had been spent fixing the roof of the railway station redeveloped in time for the Newport Ryder Cup held in October 2010.

A Network Rail spokesman said on Tuesday: "We still have verification works to complete before we are happy that the roof is leak free.

"The station represented a £20 million investment when it was redeveloped in 2009.

"The station reopened in time for the 2010 Ryder Cup golf competition in Wales.

"Since then, we became aware of interface issues between some of the materials used in its construction.

"We agreed a remediation plan with our contractor and we are delighted that the works are now complete."

A spokesman for Arriva, which runs the station, said: "Outstanding pieces of work, including the roof are due to be finalised at Newport station by Network Rail.

"Like many new buildings, there are some issues which need to be ironed out."
