Reply to "Mixing Train Cars"

Another example of "through cars" on passenger trains: The SL-SF Meteor which ran from Saint Louis to Oklahoma City carried Pullman cars from Boston & Albany, Pennsy, and Baltimore & Ohio.  Only the Pennsy cars were repainted to match Frisco's paint scheme (which is amusing to me since Frisco ran a hodge-podge of colors).  And like many other roads, Frisco ran their cars over other lines to Florida destinations.
