This word that i came across with is located in the reading “The Tunnel Rats of Atlantic
Avenue” by Yonette Joseph in the fourth paragraph. “he believes, there is a steam locomotive lying on its side like an abandon toy train in pristine condition”

Since i now know pristine means in good condition i know why it is so important and ambition for Bob Diamond to find this ancient steam locomotive especially if it is in good condition.
