Learning Curve (LC) was the first company to produce and own the Thomas Wooden Railway brand, formerly maintaining rights to counterpart Take-Along Die-Cast models, which were sold to Fisher Price and renamed Take-n-Play in 2010. RC2, the parent company of Learning Curve, was sold to TOMY in 2012. The company was absorbed by the TOMY brand. However, the Learning Curve brand still exists, continuing to manufacture their other products.
Learning Curve originally made the models plain and basic--with little detail. But as the years passed, the models evolved into detailed to strongly echo their TV series forms.
- On the old boxes, Learning Curve stated the trains were for ages 2 to 102.
