The Repair Shop's new series continued on BBC One on Wednesday night, leaving viewers in "floods of tears" over one particularly heart-rending fix.
The latest episode saw Jay Blades and his team welcome Kate Humphries into the barn along with a 1960s child's ride-on train in need of a major restoration.

Kate explained that the train was a gift from her father, who recently suffered a stroke, and that she was hoping that metal expert Dominic Chinea would be able to restore the treasured item so that her father could watch his grandchildren play with it.
Dominic soon got to work on the train on the family heirloom but it was a bittersweet return to the barn for Kate as she revealed that her father had since passed away.
Overwhelmed with the astonishing transformation, Kate began tearing up. "I think it would have meant the world to dad," she said.
"It's beautiful. It's absolutely beautiful," she said before her young daughter, Agnes, who accompanied her on her second trip to the barn, enjoyed a ride on the newly restored item.
