Fresh from the paint shop, Soo Line Mikado No. 1003 sits in the sun in October 1959, shortly after being donated to city of Superior, Wis. But is it a USRA Heavy or Light Mikado? Neither; the USRA’s Heavy and Light designs came along after Soo Line Mikado No. 1003 was built. John H. Kuehl photo, David P. Morgan Library collection
