* Volunteers Paul Lawton and David George sprucing up the front pavement on London Road ready for the grand opening of the exhibition on Friday.
The exhibition features railway photographs and documents, together with items of former railway artefacts from the local lines around Corwen.
A digital slide show of some 200 historical local railway images is also presented.
Another feature is a display about the new build Patriot class locomotive “The Unknown Warrior”, as currently being erected at the Llangollen Railway’s engineering base.
The exhibition is organised by local author Paul Lawton and Martin Christie from Carrog station.
Paul Lawton, one of the organisers, said: "This will be the biggest railway display so far held in Corwen with many items that will interest all residents, not just railway enthusiasts.
"We all hope it keeps interest alive in Corwen's future link with the Llangollen Railway, which is so important to the town.
"The team who have pulled this together have put in a lot of effort and we hope everyone enjoys the exhibition. We really hope that people from the town will come along and share with us their memories of the railway."
Norman Jones, of the Edeyrnion Heritage and Cultural Society, said: "I am delighted that Denbighshire County Council had agreed to allow The Corwen Oriel to be used for the Railway and Art exhibitions.
"I am looking forward to other exhibitions in the future, including one proposed on the farming heritage of the Dee Valley."
Opening dates for the exhibition are September 28 – 30 and October 4 – 7, between 10am and 4pm. Admission is free.
The Oriel Gallery is in the red brick former chapel opposite the black and white Corwen Manor on London Road at the eastern end of the town. Car parking is available on the road or around the back in the town car park.
The event is supported by Cadwyn Clwyd - Rural Development Agency, Denbighshire Rural Development Plan Partnership, The European Agricultural Fund for Rural Development, Welsh Government.
