Family group posing for a travel portrait somewhere along the route of the Milwaukee Road's Pioneer Limited. The car had no rear observation platform or "brass rail," forcing the family to pose in the vestibule. The picture was taken at night, using a flash apparatus, suggesting that the passengers engaged a photographer especially to take this picture. The Pioneer Limited ran from 1898 to 1970 between Chicago and St. Paul-Minneapolis. It was a high quality train that served business travelers. The first cars were made by Barney & Smith, and were replaced by wooden Pullman cars in the early 1900s.
