  h  uuu   aaaaaaaaa???????
My God we don't have many train drivers on this group do we?
The simple matter is that the train needs to dump air to stop. The trip is there to
dump that air, whenever the driver fails to do so, when the signal, or speed proving
, is disobeyed.
Should a driver become unable to control his train, The brakes remain set, or the
dead mans handle applies the brake, or the trip applies the brake. If help does not
arrive soon, and the air fails, the trip will not save the train, if it now rolls
away forwards or backwards!
