Aaah, Gladstone! Fascinating place. It and Terowie are on my "must visit when in the area" list. (Particularly Terowie). Did-ja-know Gladstone railway yard had 3 gauges in it for many years? I must dig out my photos and scan & upload them. In fact, I'll do it now! Thanks,   
P.S. That photo on the Terowie page is pitiful. I'd better find a Terowie photo, too.
