Yep, this was a Rail Tourist Association charter held on 23 April, 1988. Drivers for the tour were Ron Scholten and Peter Bhardo (hope I got the spelling correct). Attached are a few happy snaps of the tour and details of where it ran to. With regards to the route number 69 shown at Albert Park Beach terminus--that was a favourite on fan tours for its suggestive connotation of 'something'. Lol. Another favourite route number was 0E, translating to 'nought e' or 'naughty'.

I suspect the occasion was a fan tour.
