Those trains and tracks are almost identical to the Daiso range of trains and accessories. In fact if you look at the photo's of the last set and compare it with my pictures of the Daiso products I recently purchased you will see the track not only has the same connectors it also has the 'brick' effect on the edges. Similarly the trains/rolling stock have 8 wheels/4 axles just like the Daiso range, so they are almost certainly made in the same factory.
This is for sure not a bad thing as the Daiso trains and track are reasonably well made and detailed and even if not compatible with Tomy give you some nice expansion options at very very cheap prices

Happily collecting things all my life...
