This is about a poem I have a couple questions about it and I'm horrible at understanding poems so if anyone could help me that'd be amazing <3

Story:
The Railway Train
Emily Dickinson

1 I like to see it lap the miles,
And lick the valleys up,
And stop to feed itself at tanks;
And then, prodigious, step

5 Around a pile of mountains,
And, supercilious, peer
In shanties by the sides of roads;
And then a quarry pare

To fit its sides, and crawl between,
10 Complaining all the while
In horrid, hooting stanza;
Then chase itself down hill

And neigh like Boanerges;
Then, punctual as a star,
15 Stop -- docile and omnipotent --
At its own stable door.
