<SNIP>
The stopping distance for a V set is dependant on a number of factors.
1. Weather conditions. As you would understand the on a slippery rail then
the distance would be greater owing to the wheels locking up etc.
2. Gradient of  the section concerned. From memory the gradient of the
section of the accident is 1in60 desending. Someone can correct me if I am
wrong as I don't have the curve and gradient diagram book at hand at the
moment.
3. Current state of the brake shoes, slack adjusters etc. When the brakes
were last serviced. When you put a V set into emergency brake it cuts out
the regen brake.

The urban driver would have a few seconds to react. Given the eyewitness
reports he had time to put the brakes into emergency, climb out of the cab,
and get into the passenger compartment before the accident

<SNIP>
The grade would increase the stopping distance. The distance is relative to
the factors I have said in reply to your first question.

I hope this helps
