Lionel and others seem to make some wonderfull and complex operating accessories. I have begun to get the ones I have always wanted slowly but Shirley for my layout.
It seems though that most of them have critical parts that if they either wear out or fail it renders the accesory DOA. Why then do manufacturers such as lionel use plastic gears on motor shafts that are prone to break or strip and rubber drive belts that crack or stretch over time. Most of the time with lionel anyway they have the replacement parts in stock. Some of the older out of production accessories not so much. Why go cheap on the mechanisms that power these things. You would think more robust parts and designs could be achieved in this day and age. Most accessories are not ment to be throw away toys. They are precision type toys ment to enhance and complement the trains we own. So why go cheap on the main parts?
