Many adults have complained about the TrackMaster Range and now they have made it worse. The new TM engines do not work on the Old track especially the Plarail One. You might say "get the new track". Well many of us have invested hundreds to thousands of money to have a collection. And now you are asking us to buy some more and start from scratch? NO WAY! We expected a lot from you. Please TrackMaster, be like Plarail and turn to solid materials, make new charachters and greatest moments. Go back to the old design and use better plastic. Because we have seen cheap and nasty ones. Upgrade the motors instead of using 2xAAA batteries.
