Two women are sitting in a living room and having a conversation. There are a set of train tracks going directly through the living room into another part of the house. The women aren't paying any attention to it.
Train tracks are going directly through the house rather than around the house.
Why were the tracks built inside of the house?
Something's different... is that a new lamp?

People often make small design changes to rooms, and it's usual for guests to notice that something has changed (but perhaps be unable to specifically identify the changed component). The person notices that something is different about the room (obviously: the train tracks are the unusual piece), but fails to identify it, instead pointing towards something more benign.
