Wales' longest disused rail tunnel may become a cycleway

New life planned for Rhondda tunnel closed in 1968

Wales' longest disused rail tunnel may become a cycleway and tourist attraction if a volunteer group can raise the necessary funding to reopen it.

The Rhondda Tunnel Society has been formed to try and restore the Rhondda and Swansea Bay Railway Tunnel — the second-longest rail tunnel in Wales and the 17th longest in the UK — to usefulness and response has been overwhelming.

Group chairman Stephen Mackey told Wales Online's David Owens: “Since we’ve started the ball rolling by setting up the Rhondda Tunnel Society Facebook group everybody has become tunnellers.

“I’ve had people from America in touch, it’s gone through the roof.”

The tunnel opened in 1890 to take coal mined in the Rhondda to the ports at Swansea Bay. The tunnel allowed larger train loads than would have been possible if a line had been built using the alternative, steep above-ground route.

The tunnel was closed 'temporarily' in 1968 due to subsidence problems, but the cost of repairs made reopening it unfeasible. After two years of a replacement bus service, the line of which it was part was closed in 1970. Part of the line now forms the popular Afan Valley Cycleway, a family-friendly trail that connects the mountain bike routes of the Afan Forest Park.

Connecting with those trails would be an important function of the reopened tunnel, Mackey said, and his group is inspired to believe the tunnel can be reopened by the example of the Two Tunnels project near Bath, which opened in April 2013.

“In the long term I do believe in my heart that it can reopen, because there’s a project that just happened in Bath called the Two Tunnels. It (a former railway tunnel) opened as a cycle path and thousands of people head through it every week.

“In addition, RCT council is planning a cycle path from Pontypridd to Blaencwm – and there are excellent cycle trails in the Afan Valley, so in the future cyclists could pedal from Pontypridd to Port Talbot without hitting any traffic. Imagine that.

“It could be a wonderful tourist attraction. So much has been taken from the Rhondda valley over the years – coal, jobs, factories they’ve all gone, it’s about time we had something back.”

There will be a lot of work to reach that point though. The ends of the tunnel were filled in in 1979 and nobody really knows what sort of state it's in.

The Highways Agency Historic Railways Estate plans to take a look, Mackey said.

“We were told they were going to go in but as the tunnel has not been inspected internally for many years, they were discussing undertaking a structural examination in conjunction with the Mines Rescue Service.

“They said that because of the hazardous environment of the tunnel it meant only people who are properly qualified in underground rescue techniques would be allowed to enter the tunnel.”

Neverthless, there have been at least one amateur photographic expedition into the tunnel in recent years as these pics on indicate. Tunnel explorer Steve Power took a look in 2010.

Mackey doesn'r expect the tunnel to be reopened soon though.

He said: “This will take years of hard work and hard negotiation with lots of people as we look for funding via things such as lottery grants and the like.

“That is in the future. We’ve got to keep our feet on the ground, have the tunnel inspected to see the integrity of the inside structure. It would be pointless digging out the tunnel and going in to find that it has seismic faults that can’t be fixed.”

The group is starting with a more modest aim, to restore the tunnel's original cover stone, which marked the entrance.

“When the tunnel was being covered over, the contractors who were contracted to fill in the cuttings decided to take the stone out rather than bury it,” said Mackey.

“It got lost for a couple of years and then someone found it cemented into the wall of Glyncornel Archery Club in the Rhondda. It was very bizarre. We don’t know how it ended up there."

The stone eventually ended up in a disused car park. Treorchy stonemason Dewi Reynolds is now looking after it and has offered to restore it.

“When the stone is restored it will be displayed at Treherbert station where it will stay until we have a chance of reopening the tunnel, then the stone will be placed back above it where it belongs.”

John has been writing about bikes and cycling for over 30 years since discovering that people were mug enough to pay him for it rather than expecting him to do an honest day's work.

He was heavily involved in the mountain bike boom of the late 1980s as a racer, team manager and race promoter, and that led to writing for Mountain Biking UK magazine shortly after its inception. He got the gig by phoning up the editor and telling him the magazine was rubbish and he could do better. Rather than telling him to get lost, MBUK editor Tym Manley called John’s bluff and the rest is history.

Since then he has worked on MTB Pro magazine and was editor of Maximum Mountain Bike and Australian Mountain Bike magazines, before switching to the web in 2000 to work for Along with founder Tony Farelly, John was on the launch team for and subsequently became editor in chief of Future Publishing’s group of cycling magazines and websites, including Cycling Plus, MBUK, What Mountain Bike and Procycling.

John has also written for Cyclist magazine, edited the BikeMagic website and was founding editor of before handing over to someone far more representative of the site's main audience.

He joined in 2013. He lives in Cambridge where the lack of hills is more than made up for by the headwinds.
