Send your train roaring down the track! Add the Train Motor to your train engine together with the required Power Functions parts, layout your tracks, and your train is ready to roll!

To be able to understand why LEGO has been successful for so long, just look to the name. LEGO originally got its name from founder Ole Kirk Christiansen who combed the Danish words "Leg Got" which means "play well". He later realized that LEGO in Latin translates to "I put together. The LEGO set became a standard of creative play for children worldwide, unlocking the creativity to build vehicles, buildings, cities and more. Historians point to the invention of the wheel as a major turning point in world history. The invention of the LEGO wheel had the same monumental effect in the history of LEGO, making it possible to create cars, trucks and eventually the LEGO train building set that is one of the most successful LEGO sets of all time. LEGO currently produces about 20 billion LEGO bricks a year and has sold over 400 billion LEGOs in their history -- enough for every person on the planet to have over 60 LEGOs each!

        Comments about LEGO Functions Train Motor (8866):

        This is train motor does not work with newer train sets(e.g. red cargo train) power function battery packs - it uses the older four stud 9vdc connector. It requires an older four stud 9vdc connector wire and older 9vdc battery pack to work. This train motor requires a strong current so it will not work with less than 9vdc ( e.g. two dacta solar panels in full sun will not work). The only part that isnot obsolete in this set are the axle and train rail wheels assembly which still can be used with the newer train sets.

          Comments about LEGO Functions Train Motor (8866):

          This Train Motor is for ages 7 and above. I bought it under the impression that it would work with the Duplo trains and it will not. Website has it listed for children younger than 7 years old and that is incorrect according to the package.
