Product Information

Other limitation: the parts should fit on a 200 x 200 mm building plate when printing, to allow a maximum of users to print on low-cost printers.

The straight track 4563 is 176mm in length vs the 127mm of the 6377, and the 4562 curves are 45 degree and at a tighter radius than the 6378 at 33.

Finally, remember that swapping the beginning and ending of a curve has the same displacement, so we can remove one 9-10 and one 10-9 instead of two 9-10s.

Since 12 curved pieces are needed to make a full circle, the number of left pieces minus the number of right pieces must be a multiple of 12.

Wij hebben hier uiteindelijk een eigen oplossing voor bedacht en dat werkt maar dat is niet zoals het oorspronkelijk behoort te zijn.

The one thing I've really been missing is switches with one straight and one curved route, rather than the official wye type.Use this set with the 10874 Steam Train or 10875 Cargo Train to extend the possibilities of your LEGO DUPLO train collection. Preschoolers will also love to place the red action brick on the track and make any compatible DUPLO train (including 10874 Steam Train or 10875 Cargo Train) stop when it reaches it. The 'old' system had shorter straights (4665) in addition to the long ones, so there is some precedent.
