Re: Flat Wheels in Sydney

AFAIK, wheel "flats" are due to the wheel locking up during braking, so that
it slides along the rail. Same problem in motor vehicles has been mainly
overcome by ABS braking systems - a computer detects that a wheel has locked
up and eases off the braking pressure, then re-applies it. Do any suburban
trains  in Aust. have wheel-slip detection and correction for BRAKING (as
opposed to accelerating)?
