Railroad Work Crew Postcard

Can you supply any information about this image from a postcard printed by Gerbracht, supplied by Dick and Sue Erickson?

One person is identified as John Houge, but there is no indication which member of this railroad work crew is John.   John Houge (1854-1937) came to Union Township from Illinois, married Olina (Olena, Oleva) Hettisater in 1884, and settled in Palestine Township.

Chris Murray says, The help identify: John Houge in the Gerbracht postcard picture, he is the 3rd man from the right, the older gentleman.  I did some checking and that is the correct one.  I have also talked with Sue Erickson about it.  The picture was probably taken in the 1920's, by his age.  He worked on a section gang on the railroad on the 1920 census and was 60 years old living in Ames.  The 1930 census his occupation was a check mark in the column for "laborer undocumented" in Ames, age 70 years.
