Answer:
We can say that the train is running through the tunnel while noisily whistling.
Step-by-step explanation:
Emily Dickenson's poem "The Railway Train" talks about a train that is moving through mountains and valleys. The poem, spoken by an unknown narrator, personifies the train and presents it as some super-horse and "docile and omnipotent" when needed.
In the given lines from the poem, the speaker presents the train as moving through a narrow tunnel while "hooting". The particular lines show the train moving along the tracks, running through the pass whistling in a "horrid, hooting" way.
So, we can say that the train is running through the tunnel while noisily whistling.
