In the poem "The Railway Junction" by Walter De La Mare, where might the people have come from and where might they be going?

In the evocative poem "The Railway Junction" by Walter de la Mare, an unidentified narrator sits at a railway junction through and watches people pass. Nothing is explained about the narrator except that he himself is waiting for a train, as he writes: "At the appointed hour, I shall myself be gone." Two possible destinations for the passengers are presented. They may either be traveling towards "darkening hills" or towards "distant seas." Where the people that the narrator describes have come from is not mentioned or even hinted at.
Besides the narrator, a number of people are listed as having passed through the railway junction. These include a bow-legged groom, a parson dressed in black clothing, a widow and her son, a sailor carrying a cage, a gamekeeper carrying a gun, and a beautiful woman wearing a veil. These brief descriptions indicate that the narrator barely glanced at them, as people usually do in public places. He also mentions that all of these people "mutely came." In other words, he didn't talk to any of them, and they didn't talk with each other. The narrator emphasizes that he knows nothing about them: "I nothing know why thus we met—their thoughts, their longings, hopes, their fate . . ."
In summary, there is no indication at all in the poem of where these people came from or where they are going. They are strangers observed on a train platform, nothing more. It is up to each reader to speculate about the backgrounds and destinations of these people. If you have this question as an assignment, simply use your imagination.
