Answer:
I'm going to start off by saying that I'm answering this assuming that the two stories you're referring to are "The Road Not Taken" by Robert Frost and "The Railway Train" by Emily Dickinson because these are two famous pieces and it's likely that you are referring to them.
Now, onto the comparing! Both of these stories are set in a natural, and people-free, almost lonely sort of environment. They both focus on a certain thing, whether it be a path or a train, in an environment with grass, meadows, mountains, and other such things while neglecting to mention anything relating to people. The lonely setting only serves to support the poems though, as they draw more focus to their main ideas.
These poems are different because while "The Road Not Taken" focuses on just a smaller area, a fork in a road, "The Railway Train" describes a train using personification as it moves along a whole countryside. The more pinpointed and focused setting of "The Road Not Taken" helps the reader understand what a vital, focused moment it was in the author's life it was, when they decided to choose the less-worn path. In "The Railway Train," the wider setting of a whole countryside that describes a meandering train evokes a sort of awe in the reader because it's almost like describing an adventure. This way of describing the path of the train in a wider setting helps the reader understand why the author likes watching the trains so much.
