Chatting about better times no doubt. 831 is the second oldest of the 830 series and oldest survivor, entering service in February 1960. Now mainly working the Penrice Soda limestone train. GM 1 was the first diesel-electric to operate in South Australia - or was it Australia - in 1951 and is now retired.
Lighting not great, but then 831 doesn't necessarily hang out in that spot every day.
