The remote controlled engines Thomas Percy Stanley Charlie Mavis Murdoch Gordon and James only came in a two three and four pack. When James meets Harold at a signal, he does not appear to be coupled to Hector as the trucks continue moving for about a second after James stops. The UK release of the Avalanche Escape set is missing a few risers, a burst-through door, the truck, the fossil and the Scrap Monster.

The Colin in "The Party Suprise" set was the only set that had a Thomas pull a red flatcar and Thomas pull a black flatcar.Emily, Freddie, and Spencer's Trackmaster Revolution models, as well as Crash and Repair Salty, feature their model series faces despite all having a CGI one each. Skiff now has a hook coupling on the back, meaning that when he is pulled along by an engine, he faces backwards.

Duchess' coach is the same style as the 2014 TrackMaster line before the Motorized redesign, possibly because she was designed for the TrackMaster line before the switch to Motorized. Gordon was also not the only one to have a separately coupled tender in either of the original TrackMaster ranges.As of mid 2020, the range was rebranded under the name Motorized, but the products themselves remain virtually identical, aside from variation in the track being removed. Freddie, Victor, Scruff, Stephen, Timothy, Gator, Samson, Glynn, Ryan, Mike, Philip, Etienne, Hugo and Hurricane where never rereleased in Motorised Despite having Trackmaster Revolution Counterparts. The Single pack renders are slightly more accurate, but have black siderods and traction tires not present on the actual release. Ryan's prototypes show him with the correct purple wheels, but his final design shows him with black wheels for an unknown reason.
