Rail safety - video cameras in cabs

["Ronald BESDANSKY" <ronbest@bigpond.com>]

Given that a lot of money is being spent installing video cameras in
suburban passenger trains to try to increase passenger safety and reduce
damage to railway property, would it be cost-effective to install them in
all loco and EMU/DMU driving cabs? I would envisage the camera "seeing" the
same view as the driver, and also recording train speed, brake pressure etc
(perhaps another camera pointed at the gauges).

This would reduce or eliminate disputes as to what happened and what the
driver did about it. (Like the flight data recorder/cockpit voice recorder
in planes.)

Some might argue that the idea would only be to check that the driver is
doing his/her job correctly - but no so - it would pick up such things as
"wrong-side" signal failures and cars intruding onto level crossings. It
would have been evidence of what was done to cause the Zanthus accident.

What do people think?
