MECCANO madness hit Monkwearmouth Station Museum as it was taken over by giant Daleks, London buses and more.
Volkswagen Beetles, a Tardis, trains and fairground rides were also among the creations on display as the North East Meccano Society took over the venue, attracting more than 700 visitors.
Children were encouraged to take part in drop-in sessions at the museum where they could make moving models with construction toy KNEX.
Jo Cunningham, manager of Sunderland Museums, said: “It’s always a great day when these amazing models are at the museum, and I think the parents have as much fun as our little visitors.
“Big thanks to the North East Meccano Society for coming to spend the day at the museum and bringing their wonderful creations for us all to enjoy.”
The event was part of a half-term programme of free events for families that the learning team at the museum are leading.
Children could also borrow Station Backpacks – a backpack full of fun art activities and trails to explore the museum.
Families can also visit the new Wagon Shed, complete with two immaculately restored railway wagons, a suspended miniature train set, new interactives and a 1963 classic Rover P4 car.
