Kevin wants to develop a money-spinning miniature railway attraction at Chester-le-Street's Riverside, using his steam-powered super heroes, known as The Diddlys.
Diddly Dum, a train boy, and Diddly Dee, a train girl, and Cheerful Charlie, the Station Master, all undertake international rescue missions, from their home in Tootsville.
Kevin, from Ryhope, Sunderland, has already opened a Diddlys' railway in Bognor Regis, which now pulls in 85,000 visitors a year.
The dad-of-three plans to build one on his native Wearside, after drawing up plans for the Riverside.
He said: "I used to go there as a kid, we used to pack up a picnic and spend the day down there. I can still remember it now.
"What I am planning will be open all-year around, with special events at times like Hallowe'en and Christmas. The idea is to have one railway in the South and one in the North.
"At the moment there are 250,000 a year going through Chester-le-Street and if I open, I hope to double that."
Kevin has secured a four-part book deal, aimed at three to eight-year-olds, as well as developing a 3D animated series narrated by Bernard Cribbins.
There are plans for a Christmas special – Santa's Little Super Heroes – and talks are under way for Rik Mayall, Dawn French and Robson Green to provide the voices for the characters.
Kevin, a former builder, said: "I have been working on this, my childhood dream, for 12 years. The inspiration for The Diddlys came from watching the miniature train at South Shields, so it is like coming full circle."
He added: "The support I have had has been phenomenal, it would be nice to put something back.
"I want to follow in the footsteps of Walt Disney."
The Diddlys railway attraction comes as Kevin plans a 26-episode series, penned by Tweenies writer Gordon Volke, for children's TV. He has alread secured a two-year contract with Harry Ramsden's to put The Diddlys on its children's menu.
The Diddlys are continuing as the face of the National Railway Safety Campaign throughout schools in the UK.
Kevin said: "I am still continuing with that, but I hope to have the railway up and running by next summer. I am just waiting for the decision from the council.
"I don't want any more than the two, because I don't want to dilute anything.
"I am still working on the characters, TV, books and merchandising. After this I want to take things worldwide."
A spokesman for Chester-le-Street District Council said: "As with all planning applications, the council needs to remain impartial in its decision in an attempt to balance the needs of both the applicant and the local community.
