As a child, I used to love watching Shirley Temple's movies and I was drawn to reading her autobiography, Child Star. This was one of the best Hollywood autobiographies I have ever read because of the way Shirley gave a complete overview of her life.
Definition of engineer's brake valve. : a valve in the cab of a locomotive for operating the air brake.
The brake control is actuated from a driver's brake valve. This valve is used to feed air to the brake pipe or to allow air to escape from the brake pipe. A fall in brake pipe air pressure causes a brake application on each vehicle whilst a restoration of pressure causes the brake to release.
