Analysis of Song of a Train

A monster taught
To come to hand
Amain,
As swift as thought
Across the land
The train.

The song it sings
Has an iron sound;
Its iron wings
Like wheels go round.

Crash under bridges,
Flash over ridges,
And vault the downs;
The road is straight --
Nor stile, nor gate;
For milestones -- towns!

Voluminous, vanishing, white,
The steam plume trails;
Parallel streaks of light,
THe polished rails.

Oh, who can follow?
The little swallow,
The trout of the sky:
But the sun
Is outrun,
And Time passed by.

O'er bosky dens,
By marsh and mead,
Forest and fens
Embodied speed
Is clanked and hurled;
O'er rivers and runnels;
And into the earth
And out again
In death and birth
That know no pain,
For the whole round world
Is a warren of railway tunnels.

Hark! hark! hark!
It screams and cleaves the dark;
And the subterranean night
Is gilt with smoky light.
Then out again apace
It runs its thundering race,
The monster taught
To come to hand
Amain,
That swift as thought
Speeds through the land
The train.
