Motorized

Motorized is a battery-operated toy system manufactured by Fisher-Price, Mattel in the US and was launched in Mid 2020. It is a re-brand and redesign of the TrackMaster line and is virtually identical to it, with new products being released alongside re-releases and an aim to return to producing more traditional train sets rather than primarily focusing on stunt sets.

The line underwent a light redesign in November 2021 in order to closer match the more cartoonlike designs seen in Thomas & Friends: All Engines Go, with all CGI-based products in the line being phased out in the following months.

Celebration and Storybook
These engines all have a metallic finish and are available with and without a storybook.

T&F

 * Some changes are made from the TrackMaster line:
 * Annie and Clarabel are longer than the TrackMaster versions of them released in 2016; they now resemble the original TrackMaster designs slightly more, whereas the 2016-2019 versions were simply repainted vans. Aside from moulded faces, the two also have open windows again, as well as moulded seats and undercarriage detail. Despite this, the versions included in the 3-in-1 Package Pickup Set remain unchanged.
 * The talking models of Thomas, Gordon, James and Percy have rivets and handrails to match their current renders in the series (Talking Diesel also has rivets on his sides despite lacking them), their numbers have also increased in size. These models also feature working lamps and are more proportionally accurate, and have large red buttons on their cab roofs. For the Thomas and Percy models, Joseph May and Christopher Ragland provide the voice clips of the US releases, with John Hasler and Nigel Pilkington voicing the UK versions. James and Gordon also feature tenders with removeable coal loads, with Rob Rackstraw providing the voice samples for the former. Kerry Shale and Keith Wickham both voice Gordon in their respective locations, while the former also provides Diesel's voice clips.
 * The engines' pupils are now painted rather than printed.
 * Nia's face is updated and matches the one seen in stock photos of her previous releases in the TrackMaster line.
 * Flying Scotsman's tenders no longer have the dark green strip on their chassis.
 * The Troublesome Trucks now have moulded plastic faces rather than printed or sticker faces and their bodies changed shape, with external rivets and a moulded wooden floor. Much like the cars from the Plarail Thomas and Nia and Ace Go! Go! Adventure Set, the redesigned Troublesome Trucks wobble and sway when they move, mimicking the bouncing action featured prominently in the original show's final four seasons.
 * Skiff now has a hook coupling on the back, meaning that when he is pulled along by an engine, he faces backwards.
 * He also now has the newer geared wheels that were added to most new releases beginning in 2017.
 * The fish van and Express coach in the Talking James and Gordon packs now have the same extended chassis used by Annie and Clarabel and Kenji's coaches. The Express coach also opens like the original see-inside TrackMaster wagons.
 * Percy's mail van has been updated with a grey painted roof. However, this change is only shown in the Thomas, Percy, Rebecca, & James 4-pack.
 * Rebecca's middle wheel graphic has been updated to match her wheel design from the show. However, this change is only shown in the Thomas, Percy, Rebecca, & James 4-pack.
 * 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. She also has oval buffers on the front like the real members of her class, whereas she has circular buffers in the series.
 * Kenji comes with two coaches, despite the fact that he was only accompanied by one in the series.
 * Said coaches also have their front and back swapped, so the tail lamps are facing forwards.
 * Kenji's prototype depicts him with coupling rods and grey wheels on him and his coaches with blue frames. The final release lacks the coupling rods and depicts him and his coaches with black wheels and frames. Ultimately, as his model was designed with coupling rods in mind, his wheels are exposed more than they are in real life.
 * Kenji's prototype also depicts him and his coaches with blue stripes across his windows and his roof like his basis but absent from his CGI render and his final release; this may have been part of his original design. The Single pack renders are slightly more accurate, but have black siderods and traction tires not present on the actual release. Unlike the greatest moments pack, the single pack release features bare gray plastic instead of metallic silver paint.
 * The Walking Bridge only has room for a single-unit engine. Tender engines or a single unit pulling any rolling stock will not fit. This heavily contradicts the Walking Bridge's size in the series, where it was able to perfectly fit both Toby and Henrietta.
 * Despite the All Around Sodor Deluxe Set showing the Push Along Emily with her number on marketing, she does not actually have her number on the actual toy itself. The 2021 reissue of the Push Along Emily features her 12.
 * The bar codes at the bottom of the packaging now have Thomas going up them.
 * At the inside-top of the packaging, there is a character saying the description of the set (And sometimes, a story to go along with the set).
 * The Mad Dash on Sodor set now includes two additional trucks.
 * Most sets in the back of their box now have a pun to match the description of their respective set.
 * Most sets on the side of the box have promos of the respective characters included in said set.
 * The inner flap on the sets' boxes now feature James, Percy and Nia.
 * The tanker's face in the Percy & the Tanker pack, the Talking Diesel pack and Christmas Train is based on a face from the fourth series, rather than the CGI tanker faces first seen in Journey Beyond Sodor.
 * Much like his Plarail model, Winston has a front coupling and a Sir Topham Hatt figurine, but unlike the Plarail model, the Motorized version of said figurine is not removable.
 * Terence has a TrackMaster Push Along-style coupling on his back, allowing him to couple up to compatible rolling stock. This is presumably done to allow a recreation of the scene in Thomas, Terence and the Snow where Terence pulls Thomas out of the snow.
 * Following the end of the main series prior to the reboot, the line briefly shifted to recreating moments from past episodes. It was later revealed that the engines would be redesigned to match the reboot, but the track and rolling stock would remain unchanged. Currently, it is unknown if the reboot-based range will replace or coexist with the current designs as three track sets featuring Thomas, Edward and Gordon are set for release.
 * Despite predating the release of Thomas & Friends: All Engines Go, the lift bridge in the Bridge Lift Thomas and Skiff set is based on Quickdraw Bridge from the aforementioned series, albeit with a different colour scheme.
 * A model of Percy (minus his face) and the mail car can be seen on top of a cake in the 2022 film, Smile.

AEG

 * This range of engines appear to be slightly bigger than the normal Motorized engines. This was likely done as these toys are meant for a younger audience.
 * The power switches on the engines are now red instead of silver.
 * Several of the All Engines Go sets are rereleases of previous CGI-era sets with updated engines.
 * As with the series itself, the engines' wheels no longer have spokes or side rods. However, a hole exists for side rods on the driving wheels.
 * The tenders have a new mold for their wheels, whereas the trucks and coaches retain the previous wheel mold.
 * The engines now have longer rear couplings, a feature that was only once used for the original TrackMaster model of Scruff from the original series.
 * Sandy is depicted as a cargo block in the Fix 'em up Friends set, while a version of her Push Along model is included with the Muddy Fix 'em up Friends pack.
 * Any rolling stock will be backwards compatible with the original TrackMaster and Motorized rolling stock.
 * The Bridge Lift set features a scene from Thomas Blasts Off.
 * Skiff and the Troublesome Trucks have fully molded faces due to their designs originating from before All Engines Go. This is a stark contrast to the new pieces for the All Engines Go range, which have the facial details printed on a blank face piece; the face pieces lack any molded features aside from the nose.
 * James is notably missing a whistle, unlike most of the other steam engines in the range.
 * Additionally, James' prototype incorrectly portrayed him as an 0-6-2 and his tender had a removable coal load, like the Motorized Interactive Talking James from the original series.
 * Carly's model (specifically, her battery-powered running model) features a modified crane arm design compared to her set release, that being the battery-powered running model has a straighter extendable arm to fit in the packaging bubble. She includes a flatbed to which her crane arm can be attached to let her fit under bridges and tunnels.
 * The Thomas model used for advertising the Fix 'em Up Friends set is different than the model from the set.
 * Hiro's model incorrectly has oval buffers instead of round ones.
 * The talking engines can speak to their original series counterparts.
 * On the same cake in the 2022 film, Smile, the Party Train Percy model can be seen.
 * The Percy and Bruno Pack has a modified packaging, so Bruno's face can be seen.
 * Salty's packaging features his original design on the card, as it has the silver handrails and darker body stripes.
