Referring to Galron’s remarks;
I don’t understand the remark about Xtrapolis trains. These have scrubber blocks, can be savage with wheel slips and slides, but stop reliably. Maybe you’re thinking of the Siemens issues several years back.
Driver performance should always be considered. Then again, if you hit a platform at 25km/h, go out the other end at 30 with brakes fully applied, you suspect human factors not the main problem.
The Liddiard St problem, the ATSB preliminary report shows emergency brakes applied at 97km/h, Train went through a sharp crossover, negotiated a long tight curve, lots of rolling resistance, and still took a km to stop. Going uphill. Hard to blame driver fir that.
