Very confused simple question need

the railway train
emily dickinson, 1896

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

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,
complaining all the while
in horrid, hooting stanza;
then chase itself down hill

and neigh like boanerges1;
then, punctual as a star,
stop—docile and omnipotent—
at its own stable door.

1the name of a thoroughbred race horse famous in north america in the late 19th century
