TrackMaster is a battery-operated toy system manufactured by Fisher-Price, Mattel in the US. The range was launched in 2007 after previous owners, TOMY, lost their licence to HiT Toy Company to make the Motor Road and Rail range. However, TOMY did not sell the range in the UK up until 2010. In 2010, Fisher Price picked up HiT Toys' license. The engines run on special plastic train tracks and until 2010, the roadway vehicles ran on a special grey road. In 2014, the range was redesigned. Engines are faster and run on new grey track. There are special track adapters to connect the new-style track to the old-style track. The engines can also climb up steeper inclines but can no longer free-wheel. Following the discontinuation of Adventures in late 2018, the die-cast range was modified with wheels and couplers made for TrackMaster.
Flip-face models of Gordon and Percy were seen on the back of some TrackMaster boxes, but were never released.
The Slippy Sodor Thomas' funnel is simply a regular funnel painted red.
Even though they are essentially the same engine, Charlie has a different mould instead of reusing Billy's.
Since 2010, the buffers in some sets have been depicted as a brick wall.
TrackMaster track was used twice to break the world record for the longest toy train set. The first was at the Thomas Land Theme Park in the UK in 2008 and later at The Workshops Rail Museum in Australia in 2010.
Some of the newer tender engines have their battery compartments as part of their motors, contained within the engine boiler so as to avoid having a wire that could break between the two parts of the engine. As of 2014, this change has been made to every engine as they all use the same chassis.
Since 2012, the engines have had holes in their wheels so that they can be held into the packaging by plastic sticks for security purposes. As of 2015, they still have these holes, but the sticks were only utilized with the first redesigned Greatest Moments packs.
Nelson's alloys and front beam are black instead of red.
Harvey and Mighty Mac are unpowered. A powered coach (a works unit coach for Harvey and a cream and green coach for Mighty Mac) is used to push them. This is because Harvey's crane takes up too much space to house a battery, as does Mighty Mac's end-swapping function. These engines and their respective coaches have special couplers to make them easier to push.

In the Treasure Chase Set, the sign for Arlesburgh is misspelled as "Arlesburg".
