Southern Pacific class G-100-26 gondola photographed at Lathrop, CA on March 11, 2006. We came across this freight car on our way home from Winterail -- a railfan event held each year in Stockton, CA. Photos also include Clyde King, who plans to scratchbuild a model of this car, and Elizabeth Allen, another noted and exceptionally proficient SP modeler!
I keep a 25' tape measure in the car handy for measuring dimensions on freight cars and locomotives. Clyde drew some sketches, adding dimensions where appropriate. He's since prepared a drawing for the car. Clyde is a former mechanical draftsman by trade.
