Looking for bainliest answer read “the railway train” by emily dickinson. which line best reflects the train’s playful nature?

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 boanerges; then, punctual as a star, [stop—docile and omnipotent]— at its own stable door.
