IT STARTED as a fun thing to do when he was five, but now David Cooke's model-making hobby has become an obsession.
Mr Cooke is one of a number of model makers from across the state who will show their work at the North Rail Model Expo at St Ailbe's Hall in Launceston next weekend.
The youngest exhibitor will be Sam Clarke, 10, of Westbury, who spends his spare time volunteering at Pearn's Steam World and creating models.
Mr Cooke said the event was aimed at inspiring people of all ages to get off the couch and do things.
``If people get out and about and do things, it keeps the brain stimulated,'' he said.
Mr Cooke has made two displays for the expo.
One is of the Meccano factory on Binns Road, Liverpool, and includes Hornby trains, Hornby Dublo trains, Dinky toys and Meccano sets.
The other is of Southern Britain in the 1930s.
Mr Cooke said one display to look out for was one of the old Brighton Station by Max Chandler.
Model ships, planes and Lego will also decorate St Ailbe's Hall.
