Although they might not seem like the most exciting toy on the list, spare tracks add tons of fun to existing train sets. Additional tracks let you drive the train throughout the house, around the Christmas tree and elsewhere.

What are the Types of LEGO Trains?

LEGO trains are divided into three categories (although slight overlap occurs):

  • Motorized
  • Licensed


Motorized trains move on their own power.

Older LEGO models (like the Emerald Night city train set) include an infrared remote control. It’s usually simple to operate with either a button or lever.

Newer models use Bluetooth to connect to Android or Apple devices. These types of trains usually have more features than the ones with infrared remotes. Included smartphone apps create an Augmented Reality featuring games and images. The LEGO Hidden Side series uses apps extensively.

All motorized trains can be hand-powered. If you don’t have a smartphone or the batteries in the IR remote run dry, kids can still push the train around the track by hand.


LEGO has a long and successful history with licensed properties, including Star Wars, Marvel, and Harry Potter.

Most Lego train sets based on licensed properties are from the Potterverse. Harry and his friends have many adventures involving trains. Famous scenes such as Harry’s visit to Platform 9¾ are depicted in LEGO form.

Toy Story is another popular license with Lego train sets.


DUPLO is LEGO’s line for younger kids. They’re safe for kids ages two and up. Typically, kids can play with traditional LEGOs around the age of five (but age guidelines vary by set).

DUPLO blocks are twice the length, height, and width of the traditional type. They’re easy for little hands to hold. Plus, their large size makes them extremely difficult to swallow.

Finally, DUPLO blocks, although large, attach to other LEGO bricks without a problem. As kids grow up, they can integrate their DUPLO blocks into a larger LEGO collection.

However, there’s one notable exception. DUPLO train tracks are much larger than the traditional type. A traditional LEGO train won’t run on DUPLO tracks and vice versa.

Of course, LEGO offers a huge variety of sets. If you’re looking for something without a train, check out our giant guide to the best LEGO sets for 2021.

Final Thoughts

LEGO + Trains = Fun!

Boys and girls of all ages love the best LEGO train sets. After building the sets, kids can spend hours moving the train. Plus, modern sets use apps to enhance the fun with games and images.

LEGO trains help drive creativity and imagination.
