Not strictly SA, but I just drove back from Adelaide along the Mallee Highway.
Interesting to note that, at each rail crossing on the Murrayville branch in Victoria, speed limit is reduced from the standard 100 to 60 to remind drivers of the rail line. Each crossing is also protected by flashing lights and has good visibility. In any case, the Murrayville branch only sees a handful of grain trains each year.
I assume that this is part of a statewide policy, in response to an unreasonable number of LX fatalities.
I sure hope it works.
Since we're mentioning Victoria, when a youngster back in the 60s and 70s, my family was visiting our rellies in the Wimmera. We were returning from Beulah back to Warracknabeal after dinner on a dark, moonless night. You knew you were nearing Warracknabeal when you crossed the rail line to Hopetoun. The crossing had warning signs but no lights or bells. We knew the crossing was there and Dad was slowing and preparing to check for approaching trains when it became obvious there was already a train present, leading to somewhat harder braking. No reflective strips etc on wagons back then!
That experience has stuck with me for fifty years now to the extent I'm probably overly cautious at any rail crossing regardless of bells, lights, boomgates or whatever.
I also remember the runaway train from Broadmeadows which ended up crashing into a locomotive at Southern Cross. It was going so fast that it was beating the programmed timing and passing over crossings before the gates had time to start lowering.
Regarding the Murrayville branch line, it did frustrate me about five years ago just a little that one had to reduce speed while negotiating the big S bend at the crossing west of Murrayville - as if any trains were likely to going to Pinnaroo again.
