Could it be that the train station is of more importance to you than it is to everyone else?

I live in a city with many old, historical buildings and sites and I am also disappointed when one of them disappears for something new. The scenario where they are waiting for the elderly owners to pass on is not a new concept. The heirs often are happy to have a tangible item they can sell for a profit.

As long as you are not in a position where you are personally responsible for representing the owners and their best interests, I think you are safe from feeling guilty about the events of the future.
