Buy a LEGO Train Set: Compare Age Ratings, Tracks and Functions Correctly

A LEGO train set can vary significantly depending on the child’s age and how they want to play. A train for toddlers needs easy-to-grip bricks and robust components, while a LEGO City train for older children often consists of many individual pieces and is controlled by remote control or an app. If you focus only on the appearance or a long parts list, you can quickly overlook important buying criteria.

Common pitfalls when buying a LEGO train toy

1. Age ratings and small parts are underestimated

A LEGO train for children aged 2 and over cannot be compared with a model for school-age children. DUPLO sets use larger bricks and simple functions. By contrast, LEGO City models for ages 7 and over contain numerous small parts and minifigures. The age rating is therefore not only a guide to the level of difficulty, but is also relevant to safe use.

For sets with small components, the safety warnings should be followed. Some models are expressly unsuitable for children under 3 and should be used under adult supervision.

2. “Electric” does not always mean the same thing

An electric LEGO train may be controlled by remote control, an app or a push mechanism. Before buying, check the following:

  • Are batteries included?
  • Is an app required?
  • Is a remote control included?
  • Can the train also be used without a smartphone?
  • Does the set actually have a motor, or is it a push-along train?

With the LEGO DUPLO trains 10427 and 10428, for example, light and sound effects are triggered using special action bricks. With LEGO City models such as the Police Train Heist, control is provided via Powered Up and a remote control or compatible mobile device.

3. The space needed for the track is often underestimated

A LEGO train with tracks needs more room than the packaging size might suggest. The key factor is the track once fully assembled. The LEGO DUPLO Number Train 10954 is a push-along train without a traditional circular track. The DUPLO set 10427 includes 14 track elements and can be assembled into an oval track measuring approximately 71 × 57 cm.

With a LEGO City train, you should also take the curve radius, carriage length and free space beside the track into account. With its locomotive and carriage combination, the Police Train Heist forms a track layout around 80 cm long. The Arctic set 60470 contains 22 track elements and requires considerably more floor space because of its tunnel and research station.

The most important buying criteria for a LEGO railway

Age and build size

For toddlers aged around 1.5 years and over, large DUPLO bricks and simple push-along trains are ideal. A LEGO train for children aged 7 and over is aimed at children who can already follow longer building instructions and handle smaller elements.

The number of pieces provides an initial indication of the size of the build:

  • LEGO DUPLO Number Train 10954: 23 bricks and figures according to the product description
  • LEGO DUPLO Interactive Adventure Train 10427: 57 pieces
  • LEGO City Police Train Heist 60508: 1,313 pieces
  • LEGO City Arctic Adventure Train 60470: 1,517 pieces

A high piece count is not automatically an advantage. It is best suited to children who enjoy building and want to expand their model over a longer period.

Track quantity and layout

Check whether the set includes a complete circular track, a short section of track or just individual rails. A LEGO railway with points, a tunnel or action bricks offers additional building options. Extensions can be useful if you already have a compatible train.

The DUPLO Tunnel and Track Expansion Set 10425 includes ten track elements, a set of points, a tunnel, a hopper and an action brick. It is designed for compatible DUPLO sets such as 10427 and 10428 and is not suitable as a standalone train.

Power supply and controls

With motorised models, batteries are not always included. According to the product description, the LEGO City Arctic Adventure Train Set requires 10 AAA batteries, which must be purchased separately. The DUPLO Big Interactive Community Train 10428 requires 4 AAA batteries.

For families with younger children, a train with simple push-and-go controls may be more practical. Older children are more likely to enjoy remote control, app functions and freely designed scenes.

For this age group, LEGO DUPLO sets are the best choice.

How much space does a LEGO railway need?

That depends on the model. With set 10427, a DUPLO circular track can measure approximately 71 × 57 cm. LEGO City sets with longer carriages, tunnels or stations also need additional space for play areas. Before setting up the track, you should also consider furniture edges and walkways.
