In the Face Book group:
The post was about quantum superposition that included a video.
Space Train video uses a train for a simple object as part of a simplistic explanation of a frame of reference in quantum physics, along with the platform for observers.
However a train is definitely not a quantum particle and has no quantum properties.
The train will never exhibit superposition so it is an invalid example for that.
For a correct example of quantum physics all objects should be represented in some way as particles, e.g. dots or little balls. This would reflect the domain of subatomic behaviors (i.e., no trains).
To use a massive object with no quantum behaviors is very misleading to reference those behaviors
