Duplo Trains discussion in LEGO Train Tech Posted August 8, 2016 Do you think the 10508 would be a worthwhile buy for 2 and half year old that has just started showing considerable interest in LEGO Duplo? We purchased him the 10810 Push Train and after completing his first ever (assisted) Duplo build he continued to play with the train and small track for hours. I'm considering getting him 10506, 10507 and 10508 so he can build large tracks with multiple trains... what do you think? Definitly! At least one autmatic train and some more tracks with switches will make the fun even better. Although do mind the space. I'm not sure how much flat space do you have available. Also from my experience it is good to add some amounts of simple bricks and plates so that something more can be build. From the movie he builds by his own already from the book. Mine started that much later. But if so then the extra bricks can easly change to more variation in track layout by allowing to build elevated tracks or Bridges between pices of furniture.
