HE'S a former toolmaker at Rolls Royce.
Geoff King worked on aircraft engines.
Now the Bunninadden based man looks after model railways.
A track of more than a quarter mile runs in his back garden.
In addition, Geoff-who hails originally from Watford, England,-is busy building a four-man dinghy.
Geoff said: "The model railway construction began at work.
" I suppose it came with the territory of being a toolmaker by trade.
"I was involved with local model engineering clubs.
"We built our own locomotives."
Among Geoff's collection is a Great Western 'County of Devon' engine, a Caledonian Railways 'Rob Roy' replica and a Charlatan electric model.
All are three-and-a-half inch gauge.
They pull a five-inch gauge trolly to allow 'passengers' sit and enjoy the trip around Jeff's garden.
He said: "I get kids and adults calling.
"It's an enjoyable hobby and something I've always liked doing."
Geoff moved to Sligo 17 years ago.
His wife Bridget traced some of her family graves to Ballisodare.
Geoff said: "At that stage I had retired from Rolls Royce.
"I liked the area and with the help of Roger McCarrick, Auctioneer, in Tubbercurry, we found a nice cottage just outside the village of Bunninadden.
"My love of model railways came with me and I constructed the track in the garden."
Geoff was also consulted by the nearby Ballymote Enterprise Company when a model railway was mooted for the town park.
He said: "They heard about my interest. I contacted people in England and did the paperwork, etc.
"The track came from the North of Ireland.
"It's another good attraction in Ballymote."
Away from his model railways, Geoff is working hard on his dinghy.
He said: "I'm using a model as a guide.
"Hopefully, I'll have the boat finished by the Spring.
"It will accommodate an outdoor motor and I'm looking forward to its maiden voyage
"It's something new for me."
Meanwhile....it's 'all aboard' for the railway.
