He depicts natural sensations as viewed via the window of a train compartment. According to the poet, the train travels faster than fairies can fly or witches can move. When a train moves forward, the soldiers appear to be battling foes on a battlefield. But when the train stops, they are gone.
The poet also claims that he has seen elements of his life reflected in the mill race. For example, one scene shows the poet as a young man, gazing into the water and wondering what kind of future lies ahead of him. Later, as an older man, he watches as men work on the mill. Again, he is reminded of his past self and the mysterious ways of God.
Finally, the poet notes that the mill has been destroyed many times over the years, but it keeps on spinning. This represents the eternal cycle of life.
In conclusion, the poet believes that people should not worry about their lives going on beyond this world because God will take care of them in the next.
The train is compared as armies storming into combat by the poet. Because it advances at the same rate as army men assault the enemy on the battlefield. It also represents a huge investment of time and money which would be wasted if not used properly.
Also known as a "trophy train".
In modern times, one common use for this type of train is for advertising. A company can pay to have its logo painted on the headboard of a sleeper carriage or another popular choice is having a general-purpose train fitted out with compartments containing retail shops or restaurants. These operate under private license agreements with the manufacturer or owner of record who determines their layout and pricing structure. The retailer then partners with a transportation company that can ship products to different locations within the country or overseas.
Another popular use for trophy trains is to display them during special events such as tourism campaigns or industrial exhibitions. A museum may purchase a whole fleet of passenger coaches for use in touring its collection, for example, or an industrial firm might buy several flatcars for use in promoting its product range.
And lastly, certain famous people have had their names attached to trains used specifically for their entertainment purposes.
Outside the automobile, the poet observes young trees racing by. They appear to be sprinting or running quickly. Children are gladly leaving their families. They convey a sense of vitality, energy, and activity. There is also something about them that makes the poet think they will one day grow up to be tall and strong.
In the car, though, everything is still. The driver is at the wheel but appears to be sleeping. His body is slumped forward over the steering wheel. The vehicle is trapped in traffic. No one is coming to free it up. There is no hope of getting moving again.
The poet realizes that even if the car was going very fast, it would be impossible for him to keep up with it. He would have to run to catch up with it. But what good would that do? Once he did catch up, the car would just drive away from him.
So the poet decides not to follow the car. It's better to stay where you are and read your book. Maybe when the driver wakes up he will be able to move on.
