Challenge Submission What, again?

[Brightwell]

What again, it rains.
With the howl of the gale
The bend of the tree.
The splash of the sea
And the moon quite pale.
And out of the dark comes the train.

What again, comes the light
No need to strain to see.
The much more than a spark
A rumble in the dark
It is as plain as can be.
It is the darkness of the night.

What again, comes the howl
Or was it a screech.
Was it found or lost.
Is froze in the frost.
Was it a crash on the beach.
There it is only an owl.

What again, I must travel
And with no caboose.
The clickety clack
The sinking of the track
I am again on the loose.
Another story to unravel.
