Read the poem "Travel" by Edna St. Vincent Millay. The railroad track is miles away,

And the day is loud with voices speaking,

Yet there isn't a train goes by all day

But I hear its whistle shrieking.

All night there isn't a train goes by,

Though the night is still for sleep and dreaming,

But I see its cinders red on the sky,

And hear its engine steaming.

My heart is warm with friends I make,

And better friends I'll not be knowing;

Yet there isn't a train I wouldn't take,

No matter where it's going.
