This Sept. 10, 1937 article in the Tulsa Tribune mentions an adjustable seat being refitted on one or more coaches at the Springfield shops with more to come. Anyone know the car numbers? It also hints at something I have long wondered about: In those 12 or so years when the Katy provided through service to Dallas to/from Denison, did the Frisco passengers change cars at Denison or were there through Frisco passenger cars in the consist of Katy trains?
