Need 2 sets to make a circle, can't add to other sets without additional straight pieces
on December 18, 2013
I purchased these tracks to add to our Polar Express g gauge set, and was disappointed that they form a half circle that can't be added to the existing configuration that came with the set (circle, oval) - the degree of bend in the tracks was too great for the tracks to snap together and stay no matter which way I tried. I ended up having to buy extra straight track pieces as well (sold separately) to make our track larger. Made for a frustrating 2 days until they arrived and my boys wanted to use the new track. Works fine once extra straight track added as well. Buy both and save yourself some headache!
