Now he is determined to build another legacy. For the past few years Mr Smale and the Bush Railway and Old Sawmill Trust have been working on plans to build a 2.5km bush railway in Mamaku and a 1920s historic experience at a cost of $1.5 million.
"When I tell people about it, they often think 'he's mad'," he said.
"But it will be a way for people to go back into the past, to learn more about it and just enjoy time away from the hustle and bustle of modern life."
The railway would feature a working steam train that people could ride through the bush, a saw mill used for demonstrations, an old cookhouse where people can eat food popular in the early 1900s, a petting zoo and a camping ground.
He said it would be an interactive experience for visitors, entirely different from what they would experience at local museums.
Mr Smale said a site had been chosen on Cecil Rd in Mamaku and the trust was waiting to get the lease approved by the Department of Conservation.
He hoped the project would be completed in about two years.
At 86-years-old Mr Smale said he would not be building the train or laying the tracks himself as he did with the Toot 'n' Whistle but he hoped to play a key role in the project.
"It's definitely on my bucket list. I want to see it up and running before I cark it," he said.
"I hope that it will be something for the Rotorua community to enjoy, like the Toot 'n' Whistle was. It served the community for almost 50 years, if this new railway can do the same then that would be worthwhile indeed."
Mr Smale is looking for people who might want to help fund the project on the PledgeMe website.
