- The first HO scale products released in 2002 (Thomas, Percy, James, Annie, Clarabel, Troublesome Trucks, Bertie, Harold, and Cranky) are based on promotional cartoon illustrations seen on some Thomas merchandise at the time. Terence's model also seems to be based on these images.

- Thomas, Percy, and James' HO models do not have front couplers.
- Thomas, Percy, James, Gordon, Henry, and Toby's HO models have grey coupling hooks.
- On James' HO model, the wheels and axleboxes are painted grey and his smokebox saddle is painted red when they should all be black.
- On Percy's HO model:
- The coal bunker is painted grey instead of black and is oversized.
- The cab steps are mounted on the side of the running board when they should be under the cab.
- There is no rear dummy coupling hook.
- On Duck's HO model:
- The buffer housing is black instead of red.
- The prototype model had a black footplate similar to the CGI model of Duck, but was changed to grey on the production model.
- Diesel was the first HO engine to have a CGI-style face.
- On Annie and Clarabel's HO models:
- The underframes are painted grey instead of black.
- There are no dummy coupling hooks.
- Annie, Clarabel, and Emily's coaches' HO and Large Scale models have removable roofs.
- The coaches in the Thomas' Christmas Delivery and Thomas' Christmas Special sets are Emily's coach repainted.
- Terence's HO model has a removable snowplough.
- Winston is the only character to date to be made in Large Scale but not HO scale.
- The human figures, originally marketed as HO scale, are larger than HO scale. They have since been relabeled as Large Scale items.
- The original Sodor scenery accessories used the same tooling as Bachmann's Plasticville line.
- In an official forum post, a Bachmann representative revealed they had plans to update James to look more like his on-show counterpart in 2015, but once they sent the artwork for the update to the factory, it was too late to change the production line at the time. James' updated release is due sometime in 2017.
- Thomas' HO scale model, along with Annie, Clarabel, and Emily's coaches, made a cameo in the 2015 film "Ant-Man", Several models were also shown in the teaser trailer.
- Also you can see that Thomas' face is different
- Percy's large scale prototype has a green coal bunker.
