My rule is, if a track goes at an angle, say left, it is forbidden for the next-up rail to go right, you have to add a straight line. It was actually Christiansen’s son Godtfred Kirk that saw the potential for the bricks to become a tool for creative play and in 1958, the modern brick design was born. Product 1: Show your preschooler how easy it is to place the red action brick on the track to make any compatible train, such as the 10874 Steam Train or 10875 Cargo Train, stop when it reaches it. Only reviews that feature the label "Verified Review" have been checked to ensure that the author actually used or purchased the product. A curve connects to an adjacent side plus one; not sure how to describe that better without resorting to pictures.

Show your preschooler how easy it is to place the red action brick on the track to make any compatible train stop when it reaches it. If you have 45degree curves (which I think the original duplo track system did) you end up needing strange lengths (probably factors or sqrt(2)) to make things fit and unlike Brio which has slack in it's connections, Duplo is too precise as fit.Since the 1960, thousands of sets have been released covering everything from Aliens to the Wild West.

Safety Information: Please remove all packaging attachments, and any other components which are not a part of the toy, before giving this product to a child. Note that instead of adding a piece we can remove its 180-degree rotation, so instead of adding 3-4 and 11-11 we can remove a 9-10 and 5-5. w. I removed the link in the other topic and linked to this topic instead, otherwise it might be conceived as 'self promotion' and we discourage that). I will note that the fit is just a tad snug, causing a slight lifting of the Duplo track, but if it were attached to a baseplate then it would stay flat. The irony of LEGO's design change to the shorter track segments on the 'new' track, is that the old geometry with the longer curves and straights would have accommodated left-hand/right-hand switches without any compromise or partial length track segments for correction.Other multiples would have to have some number of self-intersections, with 0, 24 and -24 all requiring at least 1, and the relative curvature of the two loops determining which one you get. Nowadays, LEGO makes a vast range of toys for all ages, as well as teaching materials for children, which are distributed in over 130 countries. What we want to do is add up the vectors from the start to the end of each piece and check that the vector sum is zero. If one loop were boosted enough to have the tie ends not touch, the interference should be eliminated.

I designed the "R2" based on the existing Y switch, but not considering a whole coherent system, as exists for traditional model railways (one of my other hobbies :) ). We don’t share your credit card details with third-party sellers, and we don’t sell your information to others. Open up endless possibilities for your toddler to make a cool track for any new or existing DUPLO train set with these LEGO® DUPLO® 10882 Train Tracks.

You can actually see it easily when comparing the bottoms of the track pieces - the wall thickness on the outer faces of the ties on the curved sections is 0. Half track sections open up many other possibilities for layouts on their own, regardless of whether new switches exist.

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. I found this very interesting site about duplo rail dimensions, which covers the basics of duplo rails.Reddit and its partners use cookies and similar technologies to provide you with a better experience. The (number of inward curving) minus (number of outward curving) sections must be 12 to join up cleanly. Use this set with the 10874 Steam Train or 10875 Cargo Train to extend the possibilities of your LEGO DUPLO train collection. e. , the vector (x=1+sqrt(3),y=-2*sqrtI(3)) is the vector (1,1,0,-2), 2021rcampion is just summing vectors.
