- Some of the characters' parts are broken or missing:
- Three of the axle boxes on Edward's tender are missing.
- Two of the axle boxes on Henry's tender are missing.
- The axle boxes on Gordon's tender are missing. His rear left buffer was previously missing, but it was repaired in 2017.
- Thomas' Pack scale model is missing his headlamp since he was displayed at Thomas Town
- In 2017, Gordon's front brake pipe had broken off and is now glued onto Edward, giving him two front brake pipes.
- Percy's whistle and headlamp lens are missing.
- Donald and Douglas' eye mechanisms were broken when they were shipped to the museum. As a quick fix, the museum painted eyes for them. Donald's tender is missing one of his buffers.
- Clarabel is missing one of her buffers, but it was luckily repaired in 2016.
- Henrietta is missing one of her buffers.
- Harold was originally displayed without his mouth, but he has since regained it and been given a surprised expression.
- The back of Ben's cab is missing, exposing his motor.
- In 2019, Oliver has lost the handrail on his left side tank, as well as his right lamp iron.
- As of 2020, Edward's whistle broke off.
- The models are displayed in the state of their last use in filming of the twelfth series. This is why some of the engines are smiling, while Gordon, Toby and Mavis have their worried face masks and Henry looks sad.
- James most likely does not have a full eye mechanism since his model was previously seen with a CGI motion tracker (used in the twelfth series to track the CGI faces on the engines while they were moving during production) while it was on display at Nitrogen Studios and is wearing a fake happy face mask.
- The museum decorates the models during Christmas.
- The models of Thomas, Annie and Clarabel were used as references for CoolProps, who are making replicas of those characters.
