Thanks acbeer91. The train I was on had the indigenous mural on the second car of the rear set.
Jordy33, yes the announcement made on the train as we passed over the bridge mentioned the lower speed was to allow the new track to "settle in". Also mentioned were the number of spans, the weight of each span ond other information. The on train staff seemed quite excited about the event.
I hadn't actually planned to be on one of the first trains over the new bridge, A mate and I had planned to do Bairnsdale, using our Seniors free travel passes some time ago and the date we chose as being suitable to both of us was Monday the 7th.
