I have lived near the Grand Trunk Western main line tracks for many years. O scale models of GTW locos in the blue scheme are hard to find.
So I ordered these GTW ex-DT&I SD38 models from Charles Ro Supply Co. and Mr. Muffin's Trains.
Video of the new LIONEL O scale Grand Trunk Western SD38 diesel engine-electric motor locomotive models.
The sounds effects have more metal on metal sounds in them than the SD40.
