LINKING THIRTEEN GREAT STATES TO THE NATION. Opinion Journal's Russ Smith pens a tribute to the recently-reopened Baltimore and Ohio Railroad Museum at Mount Clare Shops in Baltimore. He also notes what we've lost.

One exhibit that caught my eye upon the museum's reopening was devoted to the dining service of the old B&O, when passengers relaxed in club cars and had waiters carve turkey tableside. There's a snack menu from the 1960 Capital Limited, which traveled from Washington to Chicago; it offered a plate of either olives or pickle chips for 30 cents, Cokes at 20 cents, tuna sandwiches for 80 cents and a crab cocktail for a dime short of a dollar. Think about that the next time you purchase a cardboard, microwaved pizza on an Amtrak Acela or Metroliner train.

I will skip the obligatory conversion to current dollars. Economy measures in food service might be self-defeating. Right up to the end of service, the dining service on the Electroliner reported a profit.
