Learning Curve was founded in 1992. It began making several Thomas Wooden Railway models in 1992 as well; however, they were only prototypes, and the production models were released in 1993, and many have maintained active status ever since. There are rumors that say the line was first released in 1992 and the rumors have a possiblity of being true.
Learning Curve originally made the models plain and basic--with little detail.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.
- Learning Curve/TOMY was considered by many to be the top Thomas and Friends merchandising producer, having formerly produced two major lines of items. However, its monopoly was lost when the rights to produce Take-n-Play models were given to Fisher-Price.
- On the old boxes, Learning Curve stated the trains were for ages two to 102.
