Glass lined bulk milk cars were seen on Wisconsin rail lines in the mid 1930's to the early 1950's. All we see now is roadgoing bulk milk transport trucks.
Trivia: The technique used to line the rail cars cast iron tanks with glass was developed for the brewing industry by a fellow named Caspar Pfaudler. The first such tanks were made in 1887 by the Dickson Manufacturing Company, who interestingly also produced hardware for steam locomotives. Eventually Dickson merged with other companies to form the American Locomotive Company (ALCO).
