I think the last regular passenger train (actually "goods with passenger accommodation") was in 1974. The last train to Corowa was, believe it or not, an XPT set.
It ran on Sunday 24/1/1988, using the Riverina XPT set stabled in Albury. I missed travelling on it as I found out about it too late, and it was sold out. I'm sure it was the most people ever to alight from a single train arriving in Corowa! It was preceded along the branch by a little red fettlers trike to make sure the line was ok and clear of obstruction.
The line remained open until the early 90's as far as Brockelsby (wheat silo), which is about half way along the branch and I think the last train on any section would have been a train to a gravel quarry located about 15km out of Culcairn, which I think was in late 1991.
Other snippets of info I can think of:
- commodities carried at various times include wine, wool, wheat and general freight
- a 1964 timetable I have sees two "goods with passenger accomm" services each week each way connecting to/from the Mail at Culcairn. Prior to this a CHP service also ran, but I'm not sure when this was cut back
- staff section stations were Walla Walla, Burrumbuttock, Brockelsby and Balldale
