The Hugh Napier has been brought back to its former glory
An appeal has been launched to get a new boiler for a little train which has run out of steam.
The Hugh Napier worked in the Penrhyn Quarry in Bethesda, Gwynedd, more than 100 years ago, shunting wagons of slate rubble from the quarry face to the tip.
After 50 years it was worn out and in 1954 it was dumped in a siding, finally arriving at Penrhyn Castle Industrial Railway Museum in Bangor in 1966.
A new boiler to get the Hugh Napier back on track will cost £50,000.
At one time the engine worked on the higher quarry levels knows as Bonc Ffridd, and also on the main mill level known as Red Lion.
Since it arrived at Penrhyn Castle a great deal of restoration work has been carried out with some parts being fabricated from new, like the pistons, which were made by the Ffestiniog Railway in Porthmadog.
"We want the Hugh Napier to be more than a museum exhibit," said Penrhyn Castle's learning and communications manager Marian Gwyn.
"For steam train enthusiasts everywhere this is a chance to return Hugh Napier to its full steaming glory."
Ms Gwyn said the last phase was to raise £50,000 to buy a new boiler.
"It will bring this little locomotive to life," she said.
