I took this photograph a few months ago, at the Oak Park Society of Model
Engineers,H.O Scale Model Railroad Club in Oak Park Illinois.
My recently purchased used Atlas G,M & O Alco RS 1 roadswitcher, pulls
a mid 1970's era circa 1974-1975 Illinois Central Gulf Railroad freight train.
The G,M & O Alco diesels that were acquired through merger in 1972, were
actually rolling out their last miles in ICG revenue service around this time.
